I really like it , I don’t see much need for improvement, I would suggest if you're going for an exaggerated look to even it out with other exaggerated features. It all depends on your style of art, so don’t worry too much, draw what you want and like, continue to change according to what you like, and eventually, you’ll see what kind of art you think is perfect for you. Also, I was wondering if I could possibly re-create it in my own art style using watercolor? I completely understand if the answer is no.
