Painting with light

When me and luke started taking pictures and he said we were painting with light, I had no idea what the hell he was talking about, so i just smiled and noded. When luke was explaining it to me and telling me what to do for his picture i was even more confused, but when i saw the picture i was kinda speechless, and started thinking about more creative things to do and how cool we could make this. Also when i saw the first pictures we took, it reminded me of a comic book villain in his lair, so the speech bubbles were comic book inspired. But the real meaning is within the speech bubble, i wanted the empty speech bubble to show my speechlessness for this type of photo.
