Cool! Very nice design and a nice color scheme :-) It might just be some strange effect from the camera, but the wheel arches look like they're dark green. If it's not, what set did you get them from?
Thank you for your comment! The wheel arches are in fact dark green. They are from creator set #31043. Unfortunately there is only 2 units per set. I got them on bricklinck it's much cheaper!
