hey, that’s not a bad model at all, at least it’s much better than what i can produce
my favorite way to make things real is applying gooood textures to them, and setting up a realistic lighting scene. This is because anything looks real when it feels real, and it feels real if it seems natural - it doesn’t really matter how the car looks exactly, because the weirdest cars exist and we still think its real - as long as it’s in a normal environment, our mind says.
In that way, the floor you added is better than letting it float in mid-air, but it might be even nicer to have it either in a normal environment (street or anything) or to display it like in a paper: with a white background and only the car’s shadow to see, next to the car. You can do that by
- making the world white (go to world buttons, set both colours to white)
- making your floor white (or make a new one that’s white)
- set spec of your floor to 0 (so you can’t see the light reflect on the plane there iiis no plane, only shaaaadow!)
- and finally, you need shadow (this makes your model a lot more realistic, if all goes well): in the render buttons, activate shadow and decide whether you want raytracing (it’s slower, but nicer)
> if you want to use raytracing, you need to activate the raytrace-button on the lamps you want to cast shadow, and of course activate the Ray button in render window.
> If you don’t want raytracing, use a spot-lamp. Set a lamp to spot, press Ctrl-0 in your favorite 3d-window to see what your lamp is seeing, rotate it to shine on your car and press Alt-0 to return to your Camera again.
When that’s all done, all that’s left is the ‘naturalness’ of your car. At the moment your car has a sort of not-really-ripe-yet banana colour, with no gradients in the colours (you can use colour ramps for this in your material buttons, it’s really neat), and well, the seats and the wheels are looking somewhat the same - white and very specular.
I think you can darken both, for the wheels add some darker colours at the left side of the colour ramp (this is the colour for moderately lightened parts of your wheel) and lighter colours at the right.
Furthermore, I don’t know if you’ve seen em, but I can’t recall having seen tires this flat - so maybe it looks better if you make those fatter. You can apply a texture to the tires set to nor (or disp if you have high resolution tires, -> with many many faces or subsurf), so that it’s not just rubber, but rubber with a grip :Z
Try to add some nor-textures to your seats, maybe your car, the wheels - nor-textures give the material some dents, and real-life stuff always have dents. Everywhere. You can even use a nice leather-texture to nor on your seats, so the speculars will reflect the structure of leather. And maybe try the spec, ref and cspec buttons too, instead of just nor - this way, you could (for example) create fingerprints on your window, which speculate less than glass itself (set to negative spec), for example.
Okay I’m being floody good luck!
