very very nice, I'm impressed I have trouble with 32 bit sprites and 8bit is for n00bs so, I work with 16bit, and they're ideal for my comic style
I do agree with you about the head though, there might be somthing you could do with it to make it better, but other than that, it is a beautiful sprite A+
p.s. I'm glad to hear I'm not the only spriter, if you'd like you should join the forums at bobandgeorge.com there you can REALLY show off your sprites, and the judges there are very tough, but they just eat up 32bit sprites, I'm sure you could get some great ideas from other sprite artists there too! being the few spriters here I think I'll add you to my buddy list!
