Put it in the art thread, then! I don't think I'd consider it pixel art but that doesn't make it not awesome.
Oh my god this is so bad my first sprite
1- First, let's resize this guy. What is he? Looks like a cat?
2- WHAT IN THE FLYING FUCK
3- This technique, where you put a shadow immediately next to an outline or other line, is called "banding" and is generally frowned upon in pixel art. You're trying to create a shadow in order to more clearly define your sprite's shape here, but all banding does is soften the outline of the sprite and make everything look smudgy and weird.
4- So to start, let's just get rid of it.
5- Mr. Cat is looking better already! But the blockiness of the pixels that make up his outline is even more apparent now, so how do we solve that?
6- Here's an example of a blocky line like the ones making up Mr. Cat's outlines.
7- By placing a gradient color in places where more subtle curves should appear (the technique is called "anti-aliasing"), the line looks a bit smoother.
8- But applying anti-aliasing to all of the rougher edges of Mr. Cat isn't easy, because he's kind of large.
9- Here's my attempt. Basically, try to work on a smaller level if you can. It makes it much easier to fool the viewer's eyes into thinking an outline is smooth, and it's also easier to pack more detail into the sprite since there's not as much area to focus on.
