Hello, everybody. Here is the work called “After the concert”. I’ve tried to show an atmospher of small night club. Please make critic if you don’t like any parts. It will be very usefull for me as a beginner at 3D. Thank you very much!
It certainly looks like a guitar 
If you want to know what I would do differently then I would:
a) increase the energy of the spot lamp and add some back light. The neck looks very thin because it is unlit at the back and therefore not entirely visible. Also you can still get the dark grungy look without it actually being that dark. Don’t be ashamed to illuminate the model you worked so hard on
b) the trouble is that this will illuminate your stage somewhat so you may have to work on that as it will become more visible
c) the frets look a bit chunky, and I would reduce the thickness of the wood visible around the edge of the ‘sound hole’
d) perhaps try using a real wood texture and give it a little bit of reflectivity
e) also try adding a light that shines up from the stage, only very dim, that represents the light that would naturally bounce back up. You could put an area lamp below the stage, pointing up, on the same layer as the chair and guitar but different layer to the stage itself, and tell it only to illuminate things on it’s own layer. As the guitar touches the stage I’m not sure exactly how well it would work, but you could play with it.
I’m pretty new to this so I don’t feel in a position to criticise but that’s what I would do.
Besides the setting being too empty, which doesn’t really evoke a nightclub stage, there are some significant errors in the construction of the guitar. Wikipedia has some good diagrams, and I’m sure there are many other sites with good ref material. Beginning at the top of the image:
– The headstock needs to be angled back from the front plane of the fretboard.
– The machine screws aren’t constructed properly and lack the flared “wingnut” shape.
– The nut at the head of the fretboard seems to be missing entirely
– The frets are too thick in cross-section and seem to sit too high off the fretboard
– The strings seem to be all the same thickness & material, and should be more visible overall
– The neck of the fretboard below the heel, where it attaches to the soundboard, is too thick
– There is no saddle (aka the “bone”)
– Most classic-design acoustics have a “border” around the edges of the soundboard
– The wood finish seems nearly non-existent; a thin varnish is not ony essential to preserve the wood but also contributes to sound quality. It usually increases the specularity of the surface, which can be seen by slight variations in surface flatness. Differences in varnish thickness & gloss on the body & neck of the guitar compared to the soundboard are also common.
It’s a good start but doesn’t look nearly like a finished piece, so doing some research & finding good refs (of nightclub stage performers as well!) would be useful, I think.
Thanks, guys! I’ll try to make better result taking into account your critic.
So concert go on What can you say about this new version?

Why start a new thread and remove all the earlier stuff?
EDIT: OK, seems the admins are now lending a hand to the confusion ;). Disregard previous transmission (above).
The microphone is now the center of attention in the composition. Maybe swap their places, or slide everything stage right (picture left)? Overall lighting is pretty good but the little spot-cone in the middle looks way out of place – too small, no apparent source, just kind of “What is that?” Also, the main body of acoustic guitars is often different color (and wood) than the sounding board, and it needs a little inlay around the sound-hole (common in almost all acoustics). It also looks like the thickness of the strings is reversed (a lefty??) – in most cases, the bass E (fattest) starts on the left when seen from this view, and the strings get progressively thinner and higher in pitch moving to the right.
To delete errows
Thanks, Chipmasque!
Missing ground reflections in the foreground. Short plane?
I don’t like guitar wood texture. too straight. It seems there’s no gloss in that too…
Black background is too black and too flat. Ok, it’s a strong shadow zone but imho I have to see some vague shapes.
Nice image composition now.
Certainly an improvement in many aspects. Composition is much stronger and the guitar is definitely the focus. Ending the stage within the image frame does tend to make it look like the reflections just stop for no reason, though, and I agree that some sense of what’s going on around the stage is needed. Even empty tables would be better than empty black. They don’t have to be strongly lit or even heavily detailed, just enough to give the sense of surrounding space. The woodgrain in the soundboard should be straight afaik, it’s chosen that way for its acoustic properties. I’ve seen guitars that look almost pinstriped for this reason :). It seems a bit unfinished overall, though, maybe use a slightly different color for the sides & back, and create some glossy specular highlights to indicate varnishing. The varnish for the soundboard is thinner than the rest of the body, though, so that part can be less glossy.
The machine screws, the little devices used to wind the strings tighter when tuning, aren’t built right, though, at least not in a modern design. Google “guitar construction” for some excellent refs on how they’re built, and the woods used, etc. Knowing your subject is an important part of this kind of image-making.
