Wow, thank you for all the links!!
Before I comment and look at the links, I just want to make sure I understand your colour ideas... So, I'm kind of a 'spell-it-out' person, so... A light pink coat and a darker purple mane? Maybe a gradient to blue, then? I'm not sure about accessories... Maybe the ribbon of her cutie mark can be blue then. But, her cutie mark is white flowers, wouldn't that be too much of the same value?
I don't mind a green coat, or purple. I'm just wanting to make sure she's at least somewhat unique, and not too similar to any other ponies.
I like SugarShock, the circle gradient behind the cutie mark might be what I need for my pony.
Leily is adorable, but the pink/red is a bit too much for me.
Pinkuh is super cute!! The pink/purple is cute.
Thise are the few that stood out for me.
Name wise; Something foreign? I don't want to be weaboo and call her Sakura Momoko-chan, y'know? D: That's what I think of when I hear foreign, sorry! I think the name will be what's the hardest part!
