Sunrise #2

I found an interesting tendency with my photos. Almost all horizontal photos are cropped for 4:3, but almost all vertical photos are 3:2.

This is because for vertically framed shots, I'm more likely to show them un-cropped, and vice versa for horizontally framed ones. May be I'm just slightly better at framing things vertically? May be it's because there's always so much horizon in my photos that 3:2 horizontal framing doesn't really work?
