Umm... sorry, Cuthalion, but I don't really understand what's going on there, and at the avatar size it's not really recognizably "invisible," just slightly faded. Can you try something simpler, without all that clutter in the background, and less opaque? Thanks!
Edit: The other thing you could do, instead of portraying the invisibility, is make him covered in bandages a la the Invisible Man. Might be simpler, might not, I wouldn't know, but that'd be fine if you'd like to do that instead.
