tu spriting en si me gusta pero usas colores... nuse como decirlo =.= por ejemplo la piel es demasiado naranja =.= nuse... no me cierra

Nice piece...
Only thing I'm seeing (or not seeing) is that the hair could use a bit more of a highlight...Though it gets by without...
Some suggestions to make it even better? 
Some of the details appears a little bit difficult to decipher. Would it be possible to add some white/gray to differentiate the leather from the bottom sole on the girl's platform shoes? The same goes for the revolver, the girl's face during closeup..etc. Otherwise, it's very well executed and congraulations on a succesful character.
awesome design and very well created =)
