Helppp!!!

Haiii^{^} I recently got a tablet and I just started doing art generally. The first was one of the first digital art that I did and the second was a recreation of the first one after 3 months. I feel proud of my progress but I feel like I can do more (^～). I need help because I dont really know how to improve myself, so please if you have any advice, I will take it and I appreciate it. Thank you!(☆^ー☆)
