Yeah man it's not easy to shade that. Cylinders can be quite difficult. Quite difficult indeed. Light traveling in a straight line and hitting some of the form but not others. It's not easy to grasp. I can't even imagine how I would tackle this problem......I definitely wouldn't consult google or do any light studies. I'm stumped. Sorry dude.
Too bad I already did, and nothing seemed to help me produce something that didn't look somewhat awkward. Looks like we're both stumped then. Good thing we have good artists here to help us both!

Anyway it's so cool and totally not lame to see Pony fans come out of the wood work and post on pixelation. Awesome. We do not see enough pony work here! You guys were in hiding or didn't know about this place for awhile. And now that's all changed. I for one see nothing wrong with loving a show about female ponies(pony's?) having wacky nonsensical adventures that are pointless no matter what gender you are. I don't find it odd, weird, degrading, shameful, sad or immature in the slightest. Your parents would definitely not have a problem with it. Who would? I truly believe and stand by this.
Fellow Jedi council, the sarcasm is weak with this one.
I certainly wouldn't 'not mind seeing more! I hope you keep posting your work forever and never mysteriously vanish. 

... Anyways, back onto my topic I guess ^_^ I appreciate all of the rest of the feedback.
@Cupcake: Not sure I agree with the leg shading there (the "stupid" one that I pointed out, at least), but that shading on the back legs/flank intrigues me. Makes it feel even more dimensional. I'll definitely have to play around with that like you did on those back legs.
@Ai: lots of great tips that I'll be sure to consider/take

Eyebrows: definitely going to do some sort of eyebrow expression once I get everything else a bit more polished, since while it makes a big difference, it's not a huge piece of work to do compared to what else I have to do. But thanks for the reminder. Lighting: thanks, I've been studying other pixel art for how they shade for subjects like this (well, not ponies, but legs and plot, et al), and I decided to apply my newfound knowledge with this pixel, but having it in a slightly less common pose, with a slightly different lighting angle than what I have done with my previous ones. Single pixel issue: thanks for the catch and the tip

I'll be sure to scan the rest of it for single pixel noise once I fix a few other things.
@Triple: Not sure I completely agree with your edit, though mostly only because you added a whole new shade for lighting (and I'm trying to keep it to only 3 for now ^_^) thanks for the edit, though.
As for my own edit based on the great insight so far, I should have something by tonight (sorry it'll take until then, I'm slow at pixeling, mostly because I'm easily distracted, stuck on a bad trackpad lately that I have yet to get efficient with, and have a lot of interruptions in my schedule today that will leave me little open free time to work on this). Thanks again, you guys are great
