Awesome Indigo, that palette is beautiful.
Couple of crits however:
-the light hitting the club seems to be comming from our right...while the light hitting the body seems to be comming from our left
-consider enlarging the club near the top by about 3px on each side (so it appears thicker...it seems like a stick compared to him right now)
-the bicept seems underdetailed compared to the rest of the body, however it might be due to the smooth look you're giving his 'core' parts (abs, bicept, inner forearm, mid pecs, etc)
-his face seems very toony right now, perhaps detailing it more would help (less sharp edges near the mouth and brow for example, visible veins?)
-possibly remove the highlights from the tail, doing so would increase the depth of the image
You've improved tremendously over this past year, this piece is a testiment to that.
