Caimar is an absolute cutie! It has the charism of a water starter and it REALLY stands out! A very original concept, name (which is totally AMAZING!) I expect some BADASS evos, something really badass that I'm sure you're going to design very easily! Great job mister!
I think I like the sheep best :3 But there's something odd about Scurley.. it doesn't look anything like a squirrel! It looks neat but not very squirrelly.. its more like a dog to be honest. I would have assumed both of the grass starters were dinosaurs if I hadn't read the comments. If anything Scorchet looks more like a squirrel.
I think your grass starter would benefit from a bit more contrast between the parts in light brown and the parts in darker brown; not much, just enough to make the difference more noticeable at first sight. Apart from that, I don't find any particular problem with the sprites and designs, the six of them are quite good
