There is a sandmartin colony on the banks of the River Dee about 10 min walk from where I live, I had previously got images of birds from the main colony but this was a single nest, newly built and only about 10-12 feet above ground level.
I would be spending a lot of time with these Sand Martins if they were so close to my house.
I like the story telling element of this picture very much. Maybe a little more separation between the adult and the young would help isolate the main subject.
Austin hit the important points well. Much to like, main concern is the separation issue. Look forward to other frames with a little more space between them.
I am a bit torn on the green. Adds some needed color, but does tend to pull the eye off to the right. Might try a version without, just to see how it works for you.
