Figure Drawing Anatomy/Shading Critique

Hii this is my first time posting on here so I'm sorry if I get anything wrong. I'm relatively new at figure drawing and I feel like I have a lot more room for improvement so I would like some outside feedback. This is just one drawing I shaded fully. Any critiques or tips for the shading, anatomy or anything else that looks off is appreciated! Looking back I feel like the shading is a bit rushed and looks muddy close up. Thank you in advance <3

(Also I'm trying to figure out if I'm linking images correctly and imgur isn't working sorry lol)
