Well, I must agree with Smirt... Potatoes arnt orange, they are more of a brown than anything, and also I wouldn't think that rims are a dark gray but would have more of a shine to them. The advice I will give you is to lower the contrast of your colors (not the gray), and also research more about light sources. Your image doesnt seem to have much of a light source nor does have much of a contrast between the colors. Also, I dont know what you plan on using it for... but if you plan on using it for graal, I must say it is totally off perspective. It looks flat with a type of "slanted" view considering the wheels.
