Yeah, it's pretty much flawless other than it being small. Great job! Try for something larger next time, I'd like to see how it turns out.

Wow, praise from the masters...      Thanks again for your comments

I see what you mean about problems with shading in the neck area...  but I'm not sure how I would fix it.  Maybe if the shades were less different?

First? It is an amazing tiny sprite, where every pixel was well placed!

Id love to see some more from you, and welcome on PixelJoint!

 Not bad for a first. I can tell you have potential, you're going towards pixelart the RIGHT way at least.

Nice for a first pixel piece. I like the dithering, but the shading needs tweaked a bit around the neck (too many shades in a small area), and some of your edges are a bit hard.

As far as anatomy goes, I think maybe its face is a bit too short.

Other than that, this is screaming for neat trotting animation :) but I know how hard that could be, hehe.
