Colored Jeep Concept WIP

Well, i was trying to do a retro design of the old wagoneer, Im trying to color it with prismacolor colored pencils.
Tell me what you think of the design, and how i can improve my coloring

it looks good so far.

Theres not really much I can say except that the set of far headlights look different than the ones on the left

The sketch is good and the ellipses for the wheels are right on but you don't have enough color down to make any kind of judgement.
