AS A PAINTER, WHAT DO YOU THINK YOUR LIMITATIONS ARE?

I need a lot more practice at seeing objects in planes instead of lines. And keeping objects focused in my head for longer periods of time. I don't know enough about the properties of colors yet. My draftsmanship is not as easily fluid as I would like it to become. I have not even attempted transparent objects and I fall short in my treatment of light, though I'm getting better. The transition between light and dark is still a little hard for me. And also I definitely need to remember to stop using my teeth as a spare brush holder.
