I am starting on a beautiful dwarf blue Iris, the reference of which is from www.mooseyscountrygarden.com used with Mary’s kind permission. It is quite pale, but has a kind of silvery sheen which made the blue look very lovely to me. Here is the initial drawing I made for this, blocking the main flower shape. This time, I made the drawing on a separate sheet of paper, so that I can be free to erase and make the drawing as accurate as possible.
Next, I refined the shape of the petals and added details. The direction of the veins is very important in defining the form of the petal, so I put some extra effort there. I hope I will be able to transfer this onto the watercolor paper without too much hassle.
