Love to see the stages of your drawings, this is very good advice. I use thumbnails but I feel like I could do more, and really, they are a lot of fun. I'm curious to hear more about the use of vellum. I see you use the vellum to re-create a drawing without the guiding lines, great. When you need to color this drawing, do you do this on the vellum? It seems to me like there would be another step of transferring it back to watercolor paper for inking etc... Or, do you use vellum knowing that a drawing on vellum would end at graphite?
