Haha, yes! That's it. That's really good. Now, I don't know if it's the browser (IE 7) or what, but the timing feels off. For example, IE and FF will animate GIF's at different speeds. Seems his face should go from nice to evil and stay evil longer, hey you might even repeat a simple looping 2-frame grimacing (like when a dog's or wolf's snout is all curled up and it's bearing its canines, you know how they're mouth will kinda quiver?) to convey an even more poingient emotion. Then I'd make his face return to normal twice as fast as it changed to evil. Right now it's an obvious reverse.
My point in advising you to increase the impact of his unexpected face-change was to reap the full propsect of the effect. At this point, it's great, but could be less passive even still. What if his eyes looked straight at us when he did it? That would make more sense to me - like he caught us in something. My ultimate concept for this would involve for him to totally change position and
spread his cape like meta knight in full dracula-style horror, but that's taking this up a few notches and I bet you're ready to move on.
Did you try re-pixeling the cape anim for yourself? The fellas here will frown on just using someone's edit - they're typically meant as examples, not a contribution. Because now, Gil can take partial credit for mini Vlad here. Do you see what I mean?
