This artist was my favorite out of the three. I love the subject matter in the painting and the tiny details.

Spreading your paint with a knife.

My art :

I used both of the techniques that are explained above in this painting. Over the paint, the details are done in metallic marker, and the glow in the dark paint bordering the mushroom, I painted on with a knife.
