CommanderD, if you want to improve at pixel art then doing pixel art at this stage actually won't help much, you need to be practicing the fundamentals, on pencil and paper, not mouse and monitor. You should download Andrew Loomis' 'Fun With A Pencil'(I will provide a link if you need one), read and learn from this and you will improve, also drawing still life (stuff around you that isn't living, like a chair or mp3 player) and from life (living things, your parents, your hand, etc.) will help you improve greatly, what I see in most of your threads are doodles from your head, which is cool that you have an imagination, but if you work on your fundamentals you could make these ideas come out more like how they look in your head.
