I dunno... Frog-Glenn looks...weird... His head looks funky. :/ He looks like a balloon or something... o_O Ah well, good job nonetheless. :) Janus and Alfador look pretty cool, though I don't think Janus looks "angry" enough... :p That may just be me though. Alfador looks nice too.
And yeah, when I saw Janus in that cutscene, I was like, "Dude, that guy is grinning from ear to ear... o_O He really, really likes telling people they're about to die, apparently... o_O" I like the sprite version better. Janus is just using his normal sprite, which has an annoyed/emo expression, instead of grinning ear to ear while he tells Crono and his friends that one of them's going to die a horrible death... o_O
(I also just don't like the anime renditions of the characters. Especially Crono and Janus. Crono probably because I hate DBZ, and yes, he does look a lot like Goku... And Janus just looks unnatural... o_O Waaaay different than the impression of his sprite to me. In my opinion, sprites > Toryiama's anime drawings)
But, uh, yeah, looking forward to Human-Glenn, Marle, and Ayla! :D (Say, could you do a chibi Lavos? His final form is humanoid... I think it would be pretty cool/cute. :p)
