Alright, personal advice: try to go for wider/longer, lighter, sweeping pencil strokes while doing outlines. It tends to result in more natural-looking, less jagged curves. Also makes it easier to erase when you try to clean up the drawing a bit. As of now, it looks to me like you're just coming down on things more vertically than you really should.
As for your software, I'd recommend looking into just getting GIMP or something similar on your PC. With a bit of practice, that might help you clean things up further, and just generally give you WAY more power and tools to work with.
Also, see if you can find some tutorials on shading for like...basic geometric shapes, at the least. A sphere may be the like most basic thing to shade, but that'll still give you at least a bare-bones understanding of how to handle lighting.
Like, genuinely, setting aside the fact that these are cookie people, you actually seem to have a better handle on body proportions and posing than I ever really managed, so you do have at least SOME of the fundamentals down, in a sense? You're just missing some key bits that have a major impact on the overall appearance.
