I always like it when people make fun of Garfield. Granted, maybe you're a fan and this is an affectionate parody. It's nice to see these two contrasting characters together. Then again, Garfield is more anime-like than normal. Anime just seems too obscure. You rarely see specific works being referenced unless they're "Pokémon" or "Dragonball Z".
The light purple shadings work really well. Looking at your other art, it seems familiar. I don't feel bad for Garfield. I like him once, but I just outgrew him. Maybe that's why he's so sad.
