most of these are butchered and completely misunderstand RBY spriting, good ones skimming quickly: jumpluff, carvahna, elekid is fine, exploud (seems to be the easiest for people to reimagine), regice, salamence, regirock, metagross too maybe, drifloon and drifblim done right for sure, uxie is pretty badass too
but I mean come on just look at rhyperior versus the one that someone did here at smogon, this sprite sheet overall is about a 2/10 overall after the real rby ones
(I would post the superior smogon sprites, but I must have mixed up picture backups at some point since I no longer seem to have it saved :()
