I'am new to this forum and what I have seen there are some lovely photos on here, I'am 16 years old and love bird photography so I hope you like this image.
A big welcome to BPN> A great place to learn and grow as a nature photographer!
Your Dunlin is well exposed, nice angle in the frame. From a composition standpoint, might crop a bit up from the bottom, perhaps 40% of the free space below the bird.
The details on the birds face are a little soft. You have good contrast which helps the impression of sharpness, but I would consider another round of sharpening.
Agree with Karl, please be sure to include your camera/lens and post processing data. It really helps us understand and critique the image.
