I have to agree about the car looking too bright, but note - too bright for THIS NEW BACKGROUND, either needs the bg lightening, or the car darkening...

As for the mods they actually look really cool, and have been very cleanly done.
And about the "looking like a quick chop" problem, I don't really think this one does that much tbh, looks good... but in future, should you want to help avoid this problem, try a colour change, I find this is the biggest thing you can do simply, and make it look like more has been done.

Overall good stuff though - keep it up

If you aim to realistic chops.. You should look many this kind of real cars, then you see that wheels are too small, exhaust hits to bumper, too low, cf-skirt is off etc.

I don't want to dispirit you, just keep up like you want. Use real tuning cars etc to reference.

this car is higher so the wheels can be bigger mine is done belgian style, as low as it gets with smaller wheels

would look better when tires are in fenders you know?
