I think a blue jean jacket color would have looked good on this sketch. You have some of that color at the top right of your colors on your sketch which would add a continuation of that color through his jacket. Other than that... this is one great looking sketch! Keep up the great work!
Thanks, I tried a blue like you said, but I don't think it works. The green might be a little bit "meh" but the blue is just too close to the other colors. I would have to rearrange the entire thing to make it work(I don't want to do that)
