Great work on posing , great work keeping the sketching process nice and rough for ideation . For proportions though, specifically in perspective , i would suggest you to add a proportion checking process during the refining part. In this part i want you to draw a box covering the dimensions of the form , and then to subdivide it into smaller parts by connecting the diagonal joins of box and drawing a cross then dividing it from there. Repeat until you got the numer of sub-divisions necessary for you . Now you could compare the "Proportions" of the parts of your subject accurately in 3- dimensions, and correct yourself by this quick and small grid. Proportions in perspective are innately hard, and you would require to self check and correct, but over time it will slowly become intuitive for you to imagine boxes and guidelines over your subject. Then you may want to skip this step from afterwards. | Artwod Feedback
