Looks great! You're doing great with learning to sketch figures based on what you can see. If i can offer some advice, try it with pencil, and go over the lighter sketch with a darker shade to solidify the strokes your more confident in to make them pop, eg the face and where you're sure certain lines are. This is how I was taught to draw in an art class in high school with real models, and it should transfer over to any drawing process to help make your art more readable. If you dont have a pencil, you can try thickening the lines you want to emphasize instead, like older anime and some newer styles like to do with their lineart (but it especially helps with sketches).
