These are not “portraits,” per se. I think they would fall under the heading of “snapshots.” But snapshots are important, too! Not every photo can be a work of art; some exist purely for the sake of documenting family memories. In this case, Leo’s ride on a carousel!
I know he doesn’t look like he’s particularly enjoying himself, but right afterward he wanted to ride again. I think he just likes to keep his feelings close to the vest.
