1. My favorite Image is the first one, with the stars behind the shed, because i put more time into that picture than any other picture both editing and shooting it.
2. While shooting the first picture i had to hide the flashlight while light painting, and also how long to leave the shutter open.
3. The timing of the light trails and when to start the shot for the city, and out in the desert, finding the right amount of light and time to leave the shutter open.
