I've had a subscription to Schoolism for a while now (thanks to Nally's Patronage for all those months) and its been enormously benificial to improving my work. As silly as it sounds, doing a basic course that teaches fundamental techniques was exactly what I needed. I was entirely self taught with digital art until I took this course. Its been great to understand more about digital art and all the options available to me.
I thought I'd share a few of the assignments I'd done. Keep in mind, for these ones they all started out with a pre made JPEG, usually a sketch, or in black and white. We'd go over the initial piece and over the course of a few hours we'd learn how to take it from basic to something entirely different. (TLDR I didnt draw the images, but I did paint/ render them.)
