Did a portrait exercise... I would love to get critical feedback from someone more experienced on what I need to improve. My drawing feels "off" somehow, but I'm having trouble seeing where the issue is - is it the accuracy of the block in? (I am trying to measure carefully maybe not doing as accurate a job as I need to be) Is it the value? Or the shape design? I'd love some feedback on what to focus on improving. Thank!

More beans. Really having trouble with the relative placement of the two ovals.. is the pelvis oval suppose to follow the contour of the buttocks?

Would love feedback on how accurate these are compared to the photo they were based on!
