Hey, I like your art!
I think you have some pretty good talent and great potential!
There is something I have noticed that I think might help: You have a lot of internal lines that define the wrinkles and curvature of the person you're drawing and the clothes they're wearing, etc. I think if you short up those lines and even remove some of them, it will make the surface you're drawing look a lot smoother. For instance, in this one, the jacket and skirt have so much definition that they look a wrinkled (like my clothes always do because I forget they're in the dryer, lol!) Try to challenge yourself and think "if I could only draw three internal lines to define the shape of this object, where would they be, and how long would I make them?"
Either way, really cool stuff! Keep up the work! :)
