Do not submit if it only took you 1 second to make. Only post if you took a long time to make a piece and if you think your piece is ready. This, is not ready, 4 pixels big deal *sarcasm*. If you haven't read the Submit Pixel Art Rules, then i think you should read it now.
"All pixel art is approved by a Pixel Joint admin to keep the gallery free from hardcore porn, spamming, hate speach and crappy doodles. You can submit as many pixel art pieces as you want at a time, but please note that only five pieces will be approved per day per pixel artist to prevent spamming. So if you submit 20 works it will take 4 days for all the pieces to all be activated. In addition to the standard terms of use there are a few guidelines you should read over before submitting pixel art:
Note: You will always be able to edit/delete your piece after you've submitted it."
Btw, for your description, how is that a megaman type of art? The pixelated art doesn't even look like a soldier.
ahahahah... this has to be some kind of joke :D
