Good looking bird, and you did a good job in getting low. A few stray grasses are unfortunately in the way. I'm finding the dark band above distracting, and would eliminate, or tone down, most of the white debris on the ground. Hawfinch is well exposed and the sharp face pops nicely against the distant BG.
Not much to add to Daniel's excellent critique. Making really good images of birds in the grass is a huge challenge. Love the sharpness and perfect EXP.
