Ok, so as time went by, I kept scrutinizing my sketch of Egwene, and I finally changed my mind about it. Thankfully I did. The old sketch was a bit too rigid, with a weird arm gesture that wasn't really my first intention. I realized I wasn't following my normal thinking process, I was thinking through all the painting tutorials I found on the net. So I erased everything and started anew.
This time, I first made the flow of things, then made a really rough sketch to let the gestures flow with the movement. And I went back to my old habit - coloring without finishing the sketch!
Well, I think I've made a good job of it, as I'm much more satisfied with the progress.
I thought I could use the time-tested process, that sketches and details come first, then colors and highlights come later. I can't! I must paint immediately! Scrap the details, I'm adding highlights right now!
