I'm no warbler expert but it looks like a Yellow-Rumped Warbler to me. Like the pose and eye contact. BG is terrific, although I might even out the RLC. I only wish the bird were on the other side of the perch, but that's a relatively minor issue. Overall very nice!
I think you did a nice job with the DOF and I love that background! I'm seeing these yellow-rumps in my yard, daily, now. While they don't eat seed from the feeders, they are curious and socialble, always trying to see what is going on, when all the other yard birds, visit the feeders. They love the bird baths and mister.
