Years ago I never would have done something like this because I'd have thought it unoriginal. But now that I am a little older and little wiser I can safely say that I no longer have any interest in being "original." I agree with C.S. Lewis that the more "original" one tries to be the less original he ends up being!
My next large scale oil painting will be "The Coronation of the Virgin", which is a theme that has always fascinated me and that I've often wanted to try to execute.
