I had not drawn any nature in 50 years, however I did draw insects at the California Academy of the Sciences in the mid sixties. This was all brand new to me. My hardest issue is the landscapes. They all come out looking very impressionistic. You will note a big difference in my warblers. The first one I only had colored pencils, so I had to order the watercolors. The last one took me a while to complete waiting for paint to dry.
I tried to duplicate the two sample watercolors. I had to wait for the watercolors to come because I was coloring with pastels and colored pencils. I have not done a watercolor in over 50 years. Here are my uploads. I had difficulty with the landscape as I realize I do not know how to make brush strokes to achieve the affect you want. Carol
