It's some weird cache problem LJ has been having. Most people will see your original icon, though some people may see what you're seeing or something entirely different still. Clear your cache once or twice (or sometimes even more) and it'll go back to normal.
I don't know the character in question so I can't give you a definite yes or no. I will tell you what I see though - a blond guy wearing a white outfit with a blue collar. The whole pic is filtered blue. This fellow looks a bit older than the one in the Aethereality pic.
I've had experience with LJ failing to show an avatar at all but I don't recall it mixing up any of my avatars with each other or someone else's avatars.
ETA: OK. This is weird. Refreshing your page caused a different avatar to show up. One that isn't in your userpics. This one's of a dark haired boy. O_o
