Hi there, well I´m not more talented that you, that´s for sure. But I love your idea, although I would like to give you some suggestions that might be of your help. Try the brush strokes are even and don't look messy, you can accomplish this by painting in the same direction or reducing the hardness of your brush. Also take care of the proportion in relation to the extremities since I feel is a little big from the shoulders in proportion to the head.
By any means my intention is to criticize your work, as I know how hard is to reach your level. Just my humble opinion.
