Rotate the rear rim counter clockwise a little bit and it should look a bit better.

Front mods are pretty cool, just there is a messy black part on the far left of it.

The new bonnet vent looks alot better than the original, you just need to mess around with the colour sliders of it a little bit (CTRL+U). It has too much purple (needs more blue)

Hope that helps, I can see you're improving so keep up the good work.

keep going =)
