Nice low angle does really help with feeling of image. Well exposed for whites, perhaps a slight loss of detail in a few small areas.
The light angles appeared to have been off to your left, leaving the shoulder area in shadow.
I might experiment with toning down the subtle highlights on the out of focus foreground rocks just a bit.
I love the turnstones with their stubby little legs. You've made a nice, sharp composition of this one. Getting down low is often the best way to get a great shot but sometimes it brings in foreground elements that might have been better left out. A little higher angle on this one might have actually looked better as you could have lost the out-of-focus rocks. Also, this image is looking shadowy around the neck and face, which is the part that needs to be bright and clear to draw the viewer. Just some simple things to think about that I had to learn myself, mostly here at BPN from Artie and the gang. Thanks.
As someone who loves to get low and dirty I appreciate the effort you put in for this image's angle. Having said this, you just have to be careful about bringing in OOF FG elements (as per Dany's comment). With shorebirds you can always pre-position yourself in a clear spot and wait for them to stroll by. Be careful also of the light angle. Here it is coming from high and left...the back is nicely lit, but the front of the subject is in shadow - try to get the sun directly behind your back if possible.
Good comp, and sharp enough as posted. Good clean BG, and a nice profile pose.
