Thanks for your input rbaleksandar, there's no such thing as too much criticism (as long as it's constructive & not nasty!). I have adjusted the animation slightly, see above. You were right about the eyebrows, they were way out on the side view. I've also made the colours more consistent through the frames, I think I have eliminated the "laser look". As for him looking a bit flat, I was kinda going for a pared - down cartoony look; there will be more details & shading later, but I wanted to get the basics right before moving on to the details. I'll be working more in the coming days to give him a more thorough overhaul. This is the first time I've tried animating like this & the subtleties are hard to get to grips with, a rouge pixel here and there can change the look significantly.
