I am not sure, whether 10 minutes is a good time frame for you right now. You are still struggling with proportions quite a bit, and neither you nor your piece gain a lot by spending time on attempting to hatch out a mediocre foundation. The shapes you found for belly, hips and thighs actually look nice, but the upper body, head and arms are oversized. Also, you don't find your lines immediately, and you don't use long lines, instead going more for a trial and error approach with quite short strokes.
I would recommend practicing one or two minute drawings for now, focusing on simple shapes and clear lines, and consciously reducing the amount of finer details you use for meassuring proportions.
Hatching properly is quite a science in itself, and it has to start from a good constructional basis, as finding a good orientation for the hatching pattern, that doesn't distract from the pose can't be immediately observed from the reference, and has to be partially deduced from abstract methods. I know that showing volume without halftones is sometimes hard, but for now you should try to keep it to a minimum until you become very confident with basic anatomy and find the excess focus to also take a first look into how lighting works, and what tones indicate which types of shade on a body.
