Thank you so much for taking the time to post your critique - I appreciate it. I really enjoy learning interpretations of my work - as it's sometimes quoted, art is a mirror, reflecting my intentions as well as the views, ideas, and imaginations of those who look at it. For that reason, I don't often explain my motivations behind paintings, and I've found that people actually rarely ask! So it's really interesting when someone tries to analyse beyond the surface appearance.
I unfortunately don't have a good digital camera, but I borrow my housemate's DSLR from time-to-time to take photos of completed paintings. You've just motivated me to borrow it and capture a better representation of this one!
