One of the reasons I prefer abstract art is that it is (for me) more about intuition and what I'm feeling in the moment than any sort of plan. I don't sketch out a preliminary version of what the shapes and colors will be.
And I definitely don't know anything about color theory, balance, composition, etc. aside from what is just innately pleasing for ME to look at.
So. Here is something I made a couple of weeks ago using some oil pastels and a few blending sticks.
