I'm debating changing the colours of two of my pets (possibly three) and I've love some outside input:
Arisen: I do like the slightly wary, unfriendly - perhaps even arrogant - look of the Bloodred Montre for him, but... I was thinking of changing it to something else, maybe another Bloodred pet like the Irion or perhaps even a Graveyard like the Fester. Wings are important, since he has wings in his story. Arisen's character is a narcissist and a sociopath; he's incredibly arrogant and doesn't care about other people, just what they think of him, but he's good at putting up a front that makes others think he's a nice, friendly guy. Or was, since he eventually goes insane with jealousy and ends up desperate, washed-up and paranoid. He's also a scientist who's obsessed with diseases and ends up worshiping the god of disease and decay - hence the Graveyard choices.
Jhary-A-Conel: I was thinking of something cheerful like a Spectrum or exotic like a Neela. Or even something with a hint of magic like the Galactic. Maybe I should wait and see what the Neela's special colours look like. Jhary is a dandy and a traveler of space/time, always ending up in different parallel universes and getting into adventures. He's a rather cheerful, laid-back type and somewhat mysterious; he looks like a young man but he's obviously a lot older than that. A bit like the Doctor in that respect.
I was also thinking of changing Persephone's colours. I am fond of the Glade Jollin, but it doesn't really fit with her theme and profile unless I get an overlay. I was thinking maybe a Reborn or Nostalgic Jollin?
I think either Graveyard Fester or Graveyard Irion work for Arisen.
For Jhary-A-Conel:


Less cheerful, but more masculine (dunno if he is "masculine" but just in case it appeals to you...), and more exotic:

For Persephone, Glade seems fine to me. Fiery Reborn doesn't seem very fitting. Nostalgic is neat, though I don't know if it's necessary x: But that's merely my opinion.
