Tangentially related; remember the much maligned Zed Shaw? Nobody talks about him any more. He's been doing some game dev streaming on Twitch, and I just found out he's got a 7 hour video on how to draw for complete beginners, which I am enjoying quite a bit actually: https://www.youtube.com/watch?v=NLakoYhiWko

From what I understand of pixel art, it demands all the techniques of drawing on top of trying to create a recognizable shape with only a few pixels and colours. From your question, it sounds like you're jumping directly onto pixel art without a solid foundation on drawing techniques, and I'd suggest to focus there — at least that's what I'm doing with my personal learning path.
