Also wondering about Evil Eye's Strago should I edit that or use it as a base?
I'm not sure what the difference is. My reason for making that was to illustrate a few key points which are hard to get across via critique.
The problem with using my edit as a base is it will look totally different then your own art, so you'll have this huge style inconsistency.
Your latest sprites still show the same problems. Poor colors which are too similar and dull to really give any clarity or life to the picture. Large areas of almost similar colors layered together creating indecipherable detail. Pillow shading. Areas which are too dark so as to draw your attention to them in a way that is distracting. Not to say they're bad, but they really suffer because of these deficiencies.
I recommend just trying your hand at one sprite, posting it here and letting us critique it, then improving it based on that critique.
