Thanks. I did a little bit with acrylics in high school. Acrylic is awful. I then painted mostly geometric things with house paint a few years after that. After more than a decade, I got back into it with oils. I don't want to paint with anything else.
I am self-taught when it comes to painting. I took a number of art classes in high school and college, but that was almost all drawing. I do study how other painters I admire do things, and I do that at museums. Not a lot, but from time to time. My advice would be: paint the light. Create the dark, then paint the light on top. Don't paint objects, but the light which defines them. That's the world as we see it. The objects only exist in our heads.
