I voted for #4, but I also think she would look great with #3 or #2. I just think the playful glint in #4's eye matches the sort of personality you were looking for. =^_^=
I voted for two because all those spots look adorable and their colors go together nicely. But four was a veeeery close second for me. I love that double wyvern boy...
Thanks for the input guys! I'm a little hesitant about #4 because he doesn't have a song yet, and I don't know if Ember would make a good lead mare, but their colors match so well.
I'm the only one who voted for poor Decadence. XD I think the warm and cool color palette would look just lovely together, since he's a soft cool color and she's a soft warm color, and they share spotting. He also looks like a trickster or maybe someone who's into some mischief.
Thanks for all the votes and comments, time to start contacting stallion's owners. After considering your comments and reflecting further, I think I'll start with Decadence. Thanks for the help!
