I think it would better if his hair was blowing slightly to the right or left giving the illusion that there is movement from a breeze, i think that would make all the difference to this sculpt, nothing too drastic just a subtle change to give the impression of movement.
That iconic image of the hero standing in the wind outside castle Greyskull has that epic Masters of the universe fell to it, in my humble opinion.
Heres what i mean in this pic, his hair is blowing in the wind, its just a subtle difference that i think would improve this sculpt.
