Alert! Alert! Honesty forthcoming! All hands, brace for impact!
The colors are very simplistic (red, green, blue). And they also lack depth. The green cloak is nearly a single color, for example. The boots get drowned out by the wood stump he's on, so it may have been better to have contrasted them more. The stone work seems very, organic. And by that, I mean I can't really tell if it was meant to be part plant, or if it was supposed to be mossy covered in places. Oh look! Arrows! Again, not enough contrast. Not sure the red sword does much, either. Same for the blue hair. Oh, and there's a bow! It looked like part of the cloak decoration.
Now that I've finished ripping the mini and paint, time to rip the photo. The background was distracting. Find a single piece backdrop for the next one.
And there. I've finished being mean. Now on to the nice things.
The metallics are very nice, IMO. Skin tones aren't a problem either. The base sculpting is very nice, and I think you did a good job with the multiple levels. The roots could be thinner, but they'll do.
All in all, a well deserved 6.5 (where it stands at this writing).
