Up close, with its beak open, this goose looks almost prehistoric to me. Those are bits of grass in his mouth he was munching on. Sat in mud a few feet away on chilly overcast, misty morning at local lake. (well, chilly for San Diego! lol) Softened BG, H&S, lightened eye area, NR

He does look pretty primitive!
He is sharp,like the open bill, misty feel to background.
Could stand a tad more room on right.
Main concern is that the image is pretty dark. I would consider bringing it up about 1/2 stop, and see how it looks. The whites should tolerate that fine.
It does look rather "Jurassic"! Nice comp, and I like the open bill and nice view of the serrations. I agree the image is dark and bringing it up in post would do wonders. A couple of the paler streaks could be toned down IMO (especially more-so if you raise the exposure).
Interesting looking bill, and I like the open bill showing the 'teeth'. I see in your repost, you lightened the whole image, I would only lighten the swan.
I see you reposted as I typed. The image does look better now, but there are areas that could be lightened more...fill-flash would have helped with that to start with.
