It's hard to explain, and I don't really understand.
I didn't grow up with David Bowie, my wife did, but not me. His music and movies didn't shape me as a person, or influence me as an artist. So it was a bit of a shock that I found myself suddenly crying while talking about him with my wife. What I had been trying to say, at the time, was "He would have done more."
That was when I decided to draw something to pay my own kind of tribute. I wasn't sure what to do, except that it had to be something that was wholly my work, something that conveyed what I know of him.
I finally hit on a combination of feathers and layers and masks which felt meaningful and everything fell into place from there.
Anyway, that's it.
