chop:

there is a few mistakes
enjoy

like the idea!Colour looks a bit dull.
You need to work on cleaner selections and that will improve your chops greatly!
keep it up! ;-)

You could place the wheels more outwards to fill the arches nicer.
I'd say check out the pentool, select an arch perfectly in 2 clicks

^...wheels out would look much better, also wanted to point out teh reflections but that a repeat as well ...need to work on shading and sun blicks...those seem to be small, but VERY important to be proper.
