now the stance as well the proportions look nice, way to go!
cool sprite, I cant spot any major flaws
apart from that in both sprites u used extremly strong saturated colors in some parts (the blue in new sprite and blue in previous for boots). I suppose not picking such extreme colors as it isnt that pleasant for the eye.
Also take a look at this tutorial mono made some time ago when it comes to picking the differnet shades for ur colors: http://www.lf-empire.de/forum/showthread.php?tid=10115
