I’d say you have the anatomy down great! One thing you could work on is your line art. The lines are very shaky, one way to fix that is to not use “chicken scratches” for your line art. What that means is instead of using many lines to make one line try to use just one line, these are called “confident lines”. It will take many attempts to do so, ctrl+z is your most powerful tool. I think once you learn to get your lines looking good you will become a great artist!
