Ah, cedar elm, I was about to ask what that first tree was. I like the branch angles, my smaller Korean hornbeam grows in that fashion as well. The last display seems to have an interesting interplay between the two trees. Maybe I'm reading something into it, but the pine appears to be threatening/taunting the zelkova(?) The lean of the lower tree away and the aspect of the higher tree as it arches down toward it look like a situation is going on...
