Right, just trying to get an idea of how a car will look before i commit to building it. If it doesnt look decent, doubt id be able to sell it so probably wont end up building it. Sigh.

Anyway, just after a few comments mainly regarding if im doing the Matte black right. The contrast between the light/dark bits... is it about right? Or is the dark parts too dark?
Also anyone got any ideas on how to do a vent on drivers side headlight? Should i just take out the headlight completely? thoughts/ideas welcome =]

So far:

I still dunno what to do with the headlight lol. It needs a vent but how to do it without making it looking 'in your face'?

good brush mate

I'd say keep the shape from the headlight unit but instead of optics have it as matte black and just make a hole into it. Requires a lot fabricating if you intend to do that in reality though.

Paint looks alright but as you said, the darks might be too dark. Or at least, you're missing some of the lighting. The edge between bright and dark is too strong. It should be softer and extend further down towards the bottom of the car.
