Metang/Skarm/Blaze: Very cut-and-pastish. The angles look a little weird; although the Metang could look like it belongs on those legs; the wings are at an odd angle.
Typhlo/Metang/Bat/Whatever else: Again, cut-and-pastish. The arms look ok, although the position is awkward (I dunno about you, but I wouldn't want to hold my arms like that for a long period of time). The wings have an odd angle, not to mention are a little small, and the tail is ok, although it just looks like it doesn't belong.
Angel Charmander: Angels are simple, but nice. The halo is a little high, and the left wing looks odd. (PS. Where are the wings from? Articuno?)
Demon Charmander: Not bad. The horns are a little big; try shortening them. The wings... would look better were they spread, as this position looks odd.
*insert egg smiley here* You haven't reached good yet, but you have a lot of potential. Don't take this as an insult; I just feel you're not quite there yet.
