This was a particularly silly picture, inspired by the fact that Minerva (the catgirl in the picture) was originally in the playable character roster for Mittens 2. Delta, the chap in the background, was in the original Mittens. I thought it would be amusing to draw his reaction to seeing one of the characters that people could pick instead of him, especially given how underwhelming he was to use in the first game.

Incidentally, I always quite liked Minerva's Mittens design. Her outfit was pretty nifty, as was the fact that she was equipped with an axe, which is something of a rarity for female characters. Neither of those things are particularly obvious in this picture, though, and I would hardly describe it as a particularly impressive picture overall; I just found it amusing.
