You just need to work on a few details here and there. Overall I would say you can start doing some drawings for your own series from time to time. It has a good quality to be included as art made by the author. That being said it is not at the level of a pro artist (obviously since you just started) but it is at a good enough level for a fan to appreciate the drawing.
Ofc I am only judging this particular drawing we all know that maybe you are much better at drawing other angles or the opposite could also be true. But for arguments sake lets say your drawing level is equal no matter the circumstances.
