Congratulations! In the immortal cinematic words: If you build it, they will come.
Good deal. I think part of your appeal is that your work has a distinctly different flavor -- different from the usual and expanding the range of possibilities.
Well, your surprise is not unexpected sooner or later that's what happens, once stripped of all the angst and uncertainty and the artist gets out of the way and the art leaves home and starts its own life. Too bad we can't plan that kind of stuff happening. But it is a real treat when it does happen and a great validation.
Enjoy and congrats again!
