The Guardian - Quick Sketch Timelapse

8 August, 2022

This is a timelapse of a daily exercise in painting something quickly in less than an hour. I started doodling with Krita Paint until the figures made a word pop into my head. The word was Guardian. So, of course, a dragon would guard whatever treasure is casting this moody purple light.

Study (copy) of Frazetta's Death Dealer

31 July, 2022

I did this study of a part of the original Death Dealer painting by the master of fantasy art Frank Frazetta.

This was from a book so the printed colors were either off or the other versions I've seen are off. Unfortunately, I haven't had a chance to see it in person so I can't verify.

Painted alla prima on a piece of gessoed bristol paper.
