Posting your art directly is the first mistake, the custom is that a third person has to post your art, then it get approved.
To expand on FRien's comment, this custom is because many artists that post their own work here tend to overestimate the quality of their work. It's still allowed, but your work may be judged more strictly because of this.

And the way you put the source is problem too
When uploading from your own device, the filename will populate the source field. In cases like this, you would typically replace the filename with the URL of your upload (or a title/description for a non-web source). However, since this is a self-upload, a source is not required and the field can be left blank.
Thank you all so much for the input about tags! I'll do better in future to make sure everything is filled out more correctly! Sorry for the trouble but i'm greatful for the explanations!
