Re: STAR WARS PROPAGANDA site and my personal gallery.
Can you take more detailed pictures of your Emperor, the lighting in the ones you have up doesn't show off the textural details too well, love to see the work that was put in there.
I get what you're saying on the expressions, it is more a common sight to see flatter faces then smirks, snarls, grins, etc.
Depending on character though, it can be more fun to have expression. I like the realism of your Maul portrait, and the pose you mimicked from publicity is really nice and the portrait is great for that. Being just a head, I like the the Maul bust is grinning, one of my favorite shots of him is during a pause when he's fighting Qui-Gon solo and he just snarls at him before twirling his saber and going in for the kill, similar look on him when he Force hurls the battle droid at the doors from the hanger before twirling his saber and taking defensive posture against Obi-Wan. Maul's aggressive fighting style and the visual look of his face are what appeal to me most about the character so I love that the bust I own immediately pulls me into those scenes/shots that I fell in love with the character over.
