The size is better, but there are some long flat lines on the head that should be rounded out more. Also, I didn't mention it before, but should the end of the tail be pointing in the same direction as on the front sprite?
It's very good! The shapes of the top and left sides of the head seem kind of strange, but that aside, I'm impressed! A lot of people make their sprites too large or small, or they don't look like Pokemon at all.
