Awesome work. Personally the lighter shades on the face seem a little to light in contrast to the overall skin tone. But in the case of a close light sourcethe skin would look like that.
Is this a true vector? I see most places you did pen tool (or illustrator), but in some spots like above the feather and the hair shadown it looks like you used a brush. Did you use the pen tool then put glow or shadow or something? Overall: Narly
Pentool, gradients, and a bit of brushing, as birdman pointed out (under his hair). All done on PS. NOT a digital paiting... And thank you again for the comments. <3
