Lately, I've been focusing on some basic painting principles. I'm realizing that legibility in a painting is really crucial. The ability to read what is going on and to simplify elements when necessary is what I am focusing on. A beautiful painting doesn't need to be filled with details because it needs to work as a whole first; this is why a great painting looks good even as a thumbnail sized image.
There's always so much to juggle in a painting (especially en plein air): drawing, composition, values, colors, brushwork. I feel like simplifying those elements is the highest order. There's a lot that I'm learning recently about my mindset also. To keep calm and have the painting under control is really important. These are all things that I'm continually working on.
