My latest work - I’ve pushed it as far as I can on my own. Now I’d like to see what everyone else thinks about it.
The thing I’m most worried about is composition. It’s not exactly…right. Maybe it’s too empty, maybe my camera position needs to be tweaked. I can’t tell. If anyone has any suggestions please let me know.
All comments and critiques are welcome. 
I think the lighting is what’s not “right” in this image.
It strikes me as odd that parts of the scene that are out of the light are nearly as bright as the ones right under the light. The scene overall looks a little bland, which can easily be changed with some more dramatic lighting.
In photoshop, I tweaked the levels a little bit as you can see in the before/after below:
Just work on increasing the contrast.
Your dark areas should be darker, and the light areas can get a little bit lighter, not too much though.
It looks very plain. The bricks look like they have just been laid. A bit of muck and grime would be nice I think, not heaps, but a little bit of aging would be good. Same for the ground. It kinda looks like you haven’t got a texture on that at all. Generally when there is a big thing of graf on the wall like that there is heaps of smaller tags around. Some tags on the door would look good, hoodlums love to tag doors. A bit of grime on the door would look good, too. Scratches and such as well as stains. As for the composition, I haven’t done anything with that at all so I can’t really comment on it, but it does look a bit cloudy. Keep blending!
Rule of thirds might suggest that you move the key subjects away from the centre of frame. definately grunge it up with loose rubbish blowing around and collecting in the corners, along with dirt build up in corners. The ground looks to clean also. I’ve never seen rubbish bags that look so subsurfed, generaly stuff sticks out and makes sharp points, unless they are body parts or something interesting like that.
BTW what is the point of this shot?
Thanks for all your responses!
3pointEdit, there really wasn’t much point to the shot initially. I was modeling a trash can I found in my floor’s lounge at college and the scene just evolved from it. Do you think re-evaluating the subject would help?
I think you have a pretty decent light setup there! I agree with the above suggestions. I would also add that the trash can and trash bags appear much too large. The trash can is the same width as (or wider than) the door and half as tall. The trash bags nearly the same. They seem to need to be scaled down. Door handles on common man-doors are positioned about 1/3 the height of the door, from the bottom. I think these changes would make this scene more believable, from a real-world standpoint.
Of course you can make what ever you want, I just wonder what makes this interesting? If there was some mystery there or a novel layout or stunning realism, I’d be there but…
also my plastic bags dont have that much reflec.
