I really like the top one best. Reminds me of something from the dinosaur family: a raptor? Or maybe even a little draconian. The second one confuses my senses a little bit. I see the fish but the eye seems birdlike to me for some reason. Interesting creature. I thought the 3rd one was going to be a turtle head until I saw the neck. All of them are supercool and way beyond anything I could even dream of. Nice work!
