first horse pixel

[Strawzzboy]

Here's some progress images for my first attempt at a horse. I'm not happy with the legs, the front ones especially look wonky to me. Also any ideas for getting a better mane?

Use reference. Your anatomy is obviously not good enough for guesswork at the moment. There is really no excuse not to use the amazing tool which is google image search. But I'll give you a hint. Horses have hooves, not dress shoes 

As for the mane google how to draw hair. The main idea is that hair is best represented as solid masses rather than spaghetti clumps of parallel lines which is kind of what your mane looks like.

Was about to say the same thing. Use photographs as reference, it's not a pixel art problem, it's a drawing one. Try to figure out how a horses "works", maybe work by beginning with a skeleton, then add meat.
Starting with outlines is tricky. Maybe start on paper, too. I don't know about your drawing skills, but making pixel art doesn't allow you to bypass the minimum in this domain. Good drawing => practice in pixel art => good pixel art.  No drawing => not-so-good pixel art.

Keep up!
