I want a new look for, but not sure which to go with. Any suggestions would be great. :)

do you have the pet's personality in mind? Otherwise it's more-or-less up to everyone's personal preference. Saying the name out loud gives me a feeling it could become a hydrus pet. "Mor" could be like "Mer" and "rathi" makes me think wrath. I think the legeica looks the best for that line of thinking. Fierce yet a bit elegant.

On googling her name, I see she shares it with a character from warhammer. Going that route, I would most compare her to a storm serpenth.

I have a pet for the top one named Nerobel. I'm honestly not sure though. I was trying to go with something that would be fierce and be themed to the name, but Glade seemed too tame maybe? But the Harvester looks nice for it at least.

The name seems like it would really suit a Storm Harvester. It sounds like a powerful name. The Storm Harvester looks powerful already, but the image looks like it's conjuring up a massive spell, aimed at you, and there's nothing you can do to stop it. To me it looks like it's summoning a hurricane, or perhaps something more godly.
