Awesome work. I can agree with kikindaface with the liking the unfinished work more though. I think in your finished pieces your color choices need to gradiate from warm to cool colors depending where your light source is. When you stay within the same temperature throughout, the figure/painting things start flattening out. Your values are spot on and you have awesome drawing ability. I think getting more color diversity/hues in there will take you to a whole nother level.
