I'm pretty sure this is official art. It looks like Leaf's art style, and there's the Aquaplus copyright at the bottom. Can I get a second opinion on this?

Also, I wish I knew where this image came from originally. There's gotta be a higher resolution out there somewhere!

This looks like it's more for the PS2 game release than the PC, but I'm pretty sure it's official art.

Well, I've played through the PS2 game, and unless I missed something important, this image does not appear in the game itself.
