What impresses the fancy ladies? Do they really matter?

Lots of details. Just details. What I do is paint the background one color, like Red, then use the pen tool to draw lots of lines in similar colors, like oranges and yellow. I will have some long lines and lots of little lines. It takes more than a full billing period to complete one painting and it looks like expressionist art, but the AI noble ladies love it. I started out getting $400 to $500 a painting and I'm up to way more than $1,000 a painting now and I'm not even in Act III yet.
