The number of colors is 46, not 8. I don't know what did you do, but if you want this in your gallery not just post it in the original size, but clear it. I can see some really unneccessary colors there.
I think it's better to post it in its normal size...
(then we can zoom as we please)
original size as said and try to get the colour count down, for example, you have 3 shades of gray in the chest alone, and if you look the unscaled version you can not see the colour shift, so you could combine all those colours that serve no purpose (=you can not see them) Also i must address the AA in this picture, would leave it out in most parts cause it makes the picture look messy (AA is a hard one to do correctly)...
But it has potential too, just minor adjustments... and i kind of like how you have done the fire :)
