im feeling as though there isnt enough to his design. The blue hair + blue uniform = flat, the desate midvalue gold + desat midvalue blue = flat. If you could, i would try to break him up into at very least two main values and two main colors. the gold is a good start but i think there should be more of it and brighter. also, i had liked the nice firm lines yould had on the walk cycle, id bring those back were i you. Thats all design stuff though, this one is well aligned and a significant improvement over the beginning
