Lots of good advice, thank you. Went ahead and changed the preview.

There's a LOT of stuff I need to fix! I'm gonna keep all the stuff you metioned in mind.

Thanks!

Wow, the preview does not do this piece justice. There are flaws, but the scales on the belly and the shading in the mane is really eyecatching and entertaining to stare at. The feet are very well shaped and tidy as well! I feel the muzzle is a bit unrefined near the top, though, making it look jaggy. 57 colors is excessive, and I feel you could reduce the amount of colors by a significant amount and still get the same results because there are a ton of colors that are very close to each other (mostly the very pale blues.) Lastly, I think changing the preview to the front leg area or something will give people a better idea of the scale of the piece before viewing it. As it is now, I was just expecting a headshot similar to the preview. ^^;;
