It is an MMORPG. I played it a bit at the beginning of last summer, but I don't recall ever seeing that character you have in the game itself (it's definitely not one of the playable characters, and the NPC's tended to be generic-looking, if I recall).
The wall itself isn't bad. I'm not a huge fan of orange, though, so I'm inclined to say it's a bit too orange, and I'm not sure that the bars at the top and bottom are the best matching color (if they even need to be there at all). Those are fairly minor quibbles on my part, though, and like I said at the beginning, this isn't a bad piece of work.
