Read howto:upload, kid. You should've already read it before you started uploading, but obviously not or you would've seen this:
Uploading one's own art is looked down upon. This is because it's generally thought that artists are biased when it comes to judging the quality of their own work. Only in very limited cases are such posts accepted, and posting sub-par creations of your own can result in being penalized. Understand the risks before considering posting your own work. More suitable sites to upload your own art to include Deviantart and Pixiv.
