Between the broken lower mandible and the rough primaries on both wings I'd say this individual has seen better days!! You had the right general idea comp-wise, but I'd prefer to see the tern a little bit more left, and a little lower. I also wish for a catchlight to bring the eye to life. Exposure seems fine and I like the two-tone BG.
This guy really must have seen better days. I like the soft light, wing position and BG and agree regarding putting him a bit lower in the frame and lightening the eye.
