You got some pretty nice shots here. #2 is my favorite. I do really like how you handled the light in #3. It's a great portrait shot of him, do you have a version without him in it? It would be interesting to see the difference.
All are terrific. I like the solid rock at the bottom of #1 and the presence of your nephew in the other two. Looks like some creative use of the T/S lens in #3. It works really well for me.
