I really like the 1st photo... big time. Everything is just perfectly placed within the frame (rule of thirds everywhere I look). The dog running after the boy leaving the wake which line up perfectly with the lower left corner... is just awesome. The surf in the distance is appealing to not only the boy but the viewer as my eye travels through the image.
Damn fine image that deserves liberal amounts of ink and wall space!
These bring back great memories as a kid at the beach.
Those that have dog know that both of these subjects are having a blast!
I wish on #1 the focus on the boy were sharper but you put it all together nicely on #2 and the patterns in the water and sand beneath it as well as the ripples and depth in this one are just wonderful.
