I love them both, but I feel like the first one really needs something to help make it stand out. That kinda also applies to the second one, but to a lesser extent. I like Gomi's drawings of the first, but I also agree they still need some more things to add. I suggest HUGE armored plates like on an Ankylosaurus to add to the first one's back, as well as some weird horns and spikes along the top of the head. Maybe put a bunch of quills on its back, or give it fishy scales or bird feathers? Maybe axolotl gills? A head crest, maybe similar to a Lambeosaurine Hadrosaur? I don't know, just throwing some stuff out there.
For the second one, I love the design, but the body and head kinda look a little bare. I just feel like a little something should be added there. Maybe the aforementioned Axolotl gills? Maybe make it so its mouth opens like a Sarcastic Fringehead (look it up if you have no idea what I'm talking about)? Maybe give it a dewlap like some lizards or birds, and make it big and blue like some lizards? Some kind of covering on the head, like a crest, spikes, horns, armor plating, etc? For the chest, maybe another one of those protruding bones you have on it? Maybe on the legs, add some sails that protrude along it, like old restorations of Amargasaurus or a Spinosaurus Sail? I don't know, just throwing out some weird ideas.
Don't mean to be critical, they look AWESOME. I just want to throw some ideas at ya.
If people weren't lazy, we wouldn't try to be efficient. If we weren't efficient, we'd never get anything done.
