Hi, I think this is a really great exercise to master drawing objects in different orientations. keep up the good work. I would draw bigger as the smaller it is the smaller the margin for error. l can see you are struggling with straight lines. I would do a different exercise first then move back to this one once mastered. Draw a dot in the middle of a page and starting from different points on the edge of the paper try to draw straight lines so they hit the middle dot. To help try ghosting first by hovering your pencil above the paper and only move from the shoulder. Check with a ruler after to see if straight. When doing the box exercise use a ruler at first untiI you can do it correctly without effort, then do freehand. | Artwod Feedback
