I'm really glad you like it! And you already have my permission, even though I am rather uncertain of what you mean by "lightsource" and for what program; Well, you can surprise me! Everything I do is for fun, it's free to make, and I don't mind sharing at all!
It's amazing, as your work tends to be. The concentration of focus, the noise, and the colors all blend so perfectly that I am in awe. You have yet again stunned me with your gorgeous art. Marvelous job!
