I took this using a bulb exposure in a dark room with my dad drawing a heart with a red light and my sister spelling out "LOVE" with a white one. Some of my first experimentation with bulb setting, but really fun.
The way you made it is pure fun. I tried it, too several times. We laughed a lot making this with my friends. You made it by luck, but perfect composition. Have more fun with it. Compliments.
