Thanks, Camus!
Yeah, the plasmaglobe came out okay, although it'd be way nicer if it had a buttload more frames and variation. I think it's the transparency which sells it, really. I love graphics which have something inside them, like horrid brains floating in jelly.
I think I don't like the jellyfish because the scaling in it is really cheap for the most part and the bits on top just flap around a bit. I like the transparency of it (that brain in jelly look I mentioned) but the animation is poor. But it's a sad fact when you have 30-40 sprites to do which you want to look unique and animated then
As for the blisteroid, I got the idea for it from a deeeeeeply unpleasant image on Snopes which is a faked insect infection of a breast. Really grim image, but has that lovely effect of something protruding from the skin of something else about it. The bits around the edge were just so there was a bit more movement in it, really. Not my wisest decision. (

As for the greenie, yeah, it was one of the first ones and el cheapo as a result. Doesn't really compare to the good ol' Dreadnaught. Y'know, I'm not even sure that ever got used in the game it was made for. But it does show how creatively bankrupt I am that I recycle the same themes all the time.
As for non-looping, I don't think I could ever make a long animation unless it was for a game...
