Front bumper has too much brown colour. I suggest, brush it in red colour, exactly like that You have on the side car on skirt.
Background has brown filters a little, so when You finish car, then give him brown filter too

And maybe make wheels more contrasts and darker (brighness/contrast tool)

Rly rly nice so far

The car should be half the size as it is right now, to fit the bg!

i can already imagine what the final product is going to look like, night lighting for me would be the best way to move forward, brush is perfect and vehicle lighting looks great as it is now. looking forward to the final product ^^

Shiny shiny but the lights shouldnt be reflected by that round bulbs ? Isnt a continuous light there . Just sayin` ...

i needed to change the BG, i think this looks better

Great !

Car still seems huge for me

Looks way better ..Fits better with refelctions now
