As long as you know these things its cool, welcome to PJ. Go ahead and refine your pixel (it could use a little more detailing and refinement) and then resubmit with all the proper image references.
Please read the submission rules. Pay special attention to referencing others art in your descriptions. No problem being a beginner but you don't want to start off on the wrong foot.
