would like to hear your opinion

I think this looks really good! I specifically like the shading you did on the legs. I think it would help if you were more loose with your strokes so you can accurately capture the flow of the pose, and make sure you're not pressing down hard! If you press down too hard it not only makes it harder to erase, but it'll look out of place overall. Also, don't be afraid to draw the facial features and hands in a full body pose! Other than that, I have no critiques! Well done!
