I agree with Srini - B&W may really bring out some of the cool textures on the jeep and the tire. One thing to keep an eye out for also when shooting is how things intersect in the frame... The roof, jeep side and tree kind of barely overlap - you may have been able to shift to the right to make more separation for a cleaner compostion.
I like the light coming through the roof and on the tire under "MP"
