Beginner, but tried all four. Boots twice, once with laces and once without. I only realised I'd left out the skull's spine and ribs afterwards.

I'm a beginner, but I tried all four. The boots seem to be the most complicated even though they're supposed to be a level 1 exercise, so I did them again without the laces. BTW, is there any recommendation about file size and resolution? I scanned these at 200dpi (and ferociously level-corrected them in Photoshop, or you wouldn't be able to see anything). Graphite of various hardnesses on newsprint.

The videos make perfect sense, but whenever I pick up a pencil to draw, it feels like my hand has been cut off. I don't really know what I'm doing with these.

How much use are you making of multiple Photoshop layers in this demo? Is it all on a single layer?
