Ey, Waldo in the mix! :D This really is a gathering... quality varies when you zoom in, but impressive amount of characters, and good fun to look at overall. Feels like the main title might be a bit too shrunk down though, would be cool if it had a more prominent and cental place. And the characters framed it in a bit more. Then again it does follow suit in regard to character size and all...
Also that dude in the bottom left corner, is that by any chance you yourself? The style seems to differ a bit from the rest of 'em... potential fourth wall break there. Nice work yo! Yonder Ho!
