I like this! The colors are refreshingly soft and subtle. The detail in the mane is wonderful too. C:

If I could offer a bit of critique for future reference; the coloring seems a little dry? A little variance in tones would help breathe more life into this neat creature, such as reds if you'd prefer a warmer atmosphere, or bluish grays if you want things more subtle. I guess 'saturation' would be a better word.

Nice work overall! I kind of want to sneak out of the dark and tug on its tail to see what its does. :D
