I think this is a pretty variant to Ursula. Ursella is pretty as well but also feels a bit "softer" I suppose? The "ella" makes it softer in appearance to me. I like it. It's a shame some of the other comments on here don't agree, but it is what it is. If you like it that's what matters!
Well, it's better than Ursula, the mean and super scary octopus-sea witch. I absolutely despise Ursula and this is okay, but there are MUCH better names out there.
