Hmm. I really like the potential of this, but the leaf-shadows are too dark and crisp-edged compared to his pale and soft-shaded facial features. I want to see HIM as the focus of this picture, instead of the higher-contrast shadows drawing our eyes (and attention) away as we try to figure out why he's got either continent-shaped tattoos or dark birdpoop on his head and arm.
Highest-contrast areas get the viewer's attention, which is unfortunately distracting here--and any distraction lowers the impact of a piece on your viewers.
I'd love to see you sharpen this up and repost it--both for us and for your commissioner--if you have the time, 'cause the character looks interesting and it's one of your best works here.
Thanks for the critique! I fully agree with the shadows; the style they were done in was not my choice, but I think I will change it for my personal portfolio, as I am not really a fan of how they look.
