I like the painting, nice backlighting with subtle cast shadows.
Why did you give up traditional oils, vapors? I tried WMOs but found no advantages and didn’t like the odor of them. Contrastly, found more disadvantages with them; pigment load, the need for the emulsified mixing oil, the need to soap and water wash brushes, and longer drying time.
I have some problem with regular oils solvent vapors, turps and Mineral spirits. However, Gamblin Gamsol solved that for me.
