First of all, it looks like a very promising project. I love the design!
My critiques, tips:
- the back of the car needs more work. The exhaust pipes look very strange so high up, I’d put them lower.
- the back bottom ends in a sharp edge. Curve it back under the car to soften it.
- The spoiler looks very out of place, just ‘floating’ on the car’s back. It should be attached to it somehow, like with bolts, or some other method.
- The lamps are right now just coloured coverings, there should be something under them, the light compartments with the bulbs.
Besides that the modelling looks good. One thing though: details! Its the details that make a great image. Add: rear-view mirrors, windshield wipers, maybe a license plate, plus other small details.
Materials: this one is a bit trickier, you’ll need a lot of experinmenting. First of all, turn on raytracing, both for shadows and reflections. Don’t make the common mistake of giving too much reflection for the car’s material, 0.2 should do.
The specular reflection can be a different color than white. Add a fine, grainy texture that affects only the specular values.
Add some background, like an auto-salon, that the bodywork can reflect. If not, you can add an image texture to reflect.
Lighting: best would be to use a HDR map, either with Yafray, or with ambient occlusion in Blender’s renderer. If not, one or more area lights. And one backlight todefine the rim of the car.
I’m interested in how this develops!
