Love the brush strokes, values, color, and proportions, it's all on point.
These past few paintings seem very much like fine art, have you ever used oils or made prints of these?
Personally, I'd love on of these hanging up on my wall or a high res version as a screen saver. I could definitely see these paintings hanging in a gallery too.
You mentioned on your first post that you want to make a living from art, perhaps publishing your work as a fine artist is a potential avenue of income.
Hope this helps, thanks for the inspiration!
