Portraits

Your form, and anatomy seem solid. the biggest issue I see here is lack of darks, and definition, and maybe confident lines. I see you useing full darks in some places, but it lacks the %70 darks and %50 darks. I recomend using 3 distinct values in a study (easiest if you have a grey marker and a black marker, but can be done with pensil) if you want to do it with pensil try practicing a gradient with your pensil first[img]https://www.reddit.com/r/learntodraw/comments/1issy8s/value_study_using_markers/#lightbox[/img] like this (sorry if the image doesnt show.)
if the image doesnt work, google limited value study with markers.

Best of luck!!

Thanks a lot for your insightful and helpful feedback 🙏🏼👌🏽I have no markers, I only use pencils and blending stumps (I know I go a bit heavy on the blending - I'm working on it 😅). Have a nice day 😉
