Wow! Very nicely done! I likes your style... a lot. ^^

The only nit-picky thing I have to add is the anatomy needs a little work... it looks like you enjoy drawing rather long torsos. In the first pic, also, the foreshortening is a little odd, but I really think that it could be fixed with some shading... mebbe a little line-reworking, too.

Anyway... a good way to judge body size is the average body size is 7 1/2 heads tall. ^^

Keep up the nice work! YAAY! ~gives a cookie~
