I can see your progress over your last few drawings. You're getting better.
I think you should study anatomy and how light works though. There's a book called Dynamic Anatomy by Burne Hogarth that I picked up when I first started, and it completely changed the way I drew things. To me it looks like you're drawing the skin, but not what's underneath it. It's like drawing a shirt without knowing what the body is shaped like. Extensive research and study of various things like anatomy, light and shadow, perspective, etc. are often overlooked by beginning artists, but using educational materials provided by established artists on these subjects is often not only the quickest way to improve, but also benefits your art in ways that you might not be able to do alone.
Holy moly you practically just nailed how I've been feeling these last few drawings, the skin for me always seems so flat! Thanks so much for the recommendation I shall try and find it! Im struggling with surface texture etc of skin as well as bone structure. CatCouch recommended that I do some skull studies which I will be doing soon
I'm basically starting from zero, so thank you so much for the help! Every feedback allows me to improve
I hope you have an amazing day I will be saving your comment in my advice folder
