Sketching Multiple Solutions

I was trying to come up with as many ways to show a feed of photos as possible. Predictably, my first idea was a simple grid, followed by a column of device-width photos. I tried to keep pushing to generate some unique ideas. Maybe not as practical, but the goal for me is to ensure you come up with the best idea (as opposed to the first idea). I created a simple mock up of the sketch that I thought was the most interesting.
