Couple in charcoal

Your anatomy and proportions look great, and i don't really know what style you're going for, but i would suggest improving your line confidence to give your drawings this more 'finished' look. Awesome drawing though.

This looks super impressive, and I love the shading on the background figure. If it's in your budget, I would recommend one of those drawing gloves to prevent smudges from happening. I couldn't find many solutions to it that weren't "buy product", but remembering to go through and erase those smudge marks really adds to the finished look of a piece.
