Nice! Kind of weird seeing Piggy's eye, though. She's not even looking in Kermit's direction from high up in the upper left corner, which could at least be justifiable. I suppose, upon reflection and in this edit, that the point is more to celebrate the Muppets in general, which I didn't really get to start off with. I saw Kermit, Ernie, and Waldorf first. I thought it was a Jim-related piece, which is why I was weirded out about Piggy's eye. However, upon looking again, I see Animal and Statler too.
I get a better appreciation for what the picture is about, but the prominence of Jim's characters near Jim kinda drown out the others. Having a more balanced layout might have worked better.
This was all wonderfully drawn. I'm not trying to gripe about it. It's just an observation.
