How nice of you Debe!! I must smile because that sunflower is the one and only abstract I've ever painted! I really just let myself have fun painting it and played with color:)
I've since learned that having distinct values is important - as is a good notan structure. I'm taking the Virtual Academy Art Course and am learning quite a bit --though it is very slow going because I can't do it as often as I'd like! Google whatever you can find on Not an design - that will give you a good start in developing the "bones" of your painting. Good luck!! Looking forward to seeing your work!!
