I have been doing these studies to work on drawing & value accuracy.

They are shown in the order that I painted them, left to right, top to bottom.

Numbers 1, 5, 6, 8, and 10 are copies of Masterpaintings; the others are painted from photographs, either mine, or from http://www.Unsplash.com

Most of them are in oil paint; # 8 &9 are in gouache.

This has been very instructive and helpful. I like seeing the progress through them. I know that I’ve become more accurate in my drawing, as I can do a check using the Procreate app on my ipad; I overlay my drawing at a reduced opacity on the masterpainting or photo, and can see how they line up (or don’t!). I’m making fewer adjustments for the later paintings.
