Lima looks fantastic! What did I tell ya? The jagged sail looks much better!

Nice colors, too; a little lighter and bluer than Chomper’s, and different from DarkWolf91’s
drawing of a Spinosaurus character. I also love the eye color you gave her; it’s distinct from the other characters’, and it goes well with her body coloration.
I would still suggest making her claws a bit sharper, and maybe increasing the length of her tail slightly (It could be just the angle that causes it to look a tad short in this picture :unsure). Also, her neck looks possibly a little too smooth; it had more creases and lumps in the original drawing, which gave it a more natural look there, I thought. Apart from those details, there’s not a lot of improvement I can suggest.
As for Lima’s personality, I had the impression that she would be almost like a sharptooth version of Ali; shy, playful, quick to befriend Chomper, but uncomfortable with the idea of having leafeater friends. (I didn’t even imagine her as conflicting with Ruby. :blink:) She also strikes me as being a little younger than Chomper.
Speaking of Chomper, I think he’s the one remaining character who might benefit from getting another concept drawing. All the other characters, including the ones you recently re-tooled, look terrific, and don’t need any more major alteration. However, if you weren’t already planning on taking another shot at drawing an older Chomper, I’d encourage it. The main changes I would make to
the original would be a slightly more adult-proportioned head and tail, a more mature-looking face, and possibly (an idea I just came up with that you can easily ignore) showing the spiny ridge on his back developing into the lower, smoother row of bumps seen on an adult sharptooth.
Just curious: What scene in what movie is that screenshot you used for the background from? It looks nice the way you altered it.

Thanks again, Pangaea, for coming up with some names for her. 
I'm honored to have been helpful (I honestly didn't expect that you would like my suggestions so much

). By the way, do you imagine Lima’s name as being pronounced “Lee-ma” or “Ly-ma”? I was thinking the first one when I suggested the name, but since I don’t know the exact pronunciation of the scientific name I derived it from, I suppose it could go either way.
