I haven't had too much chance to sprite lately, but I got around to it last night and today. I'm still working on the Porkring, it's about 49% complete.
As for the GM sprite, I'd say it's about 38% complete. It seems to be a never ending project. I've learned that just because an official sprite looks good animated, it doesn't mean edits will look as great, no matter how good you think they look static. :'D
