D'awww, that sheep is so cute. I think the graphics for these animals may be a little on the fuzzy side though. There seem to be "half pixels", for example. It's as if they were drawn at a larger size and then shrunk. To fit in with the rest of the artwork, the lines could be a lot more crisp (less anti-aliased and blurry). The cow looks really good but it may not be cartoony enough to fit in.
