Actually this illustrates what I have been talking about. There is not scream look, but the painting has the frown, the intent look in the eyes, head tucked and looking up like she means business. The model has a little smirk on her face. Don't get me wrong, I love your work, setting up the shot, the costuming, even the model if she was pushed to show some emotion, or that intent look of the woman in the painting.
A sorceress from Pathfinder? I really, reallly really like that class of character. it can make very interesting character backstory and bring deep and epic roleplay, if you're a roleplayer instead of a rollplayer
