Let's see....
I really love antlers. My fursona is a red deer.
I like the metallic colors of the Tesla wyrms.
The long ears of the Mountain wyrms.
I saw a black and orange banded wyrm earlier that I loved, so mine would be coppery/dark red-orange and a lighter color orange banded head. The tail would be alternating red and orange with a white or tan tail tip.
I love the glass eyes, so it would have to be a great wyrm with green or lavender eyes. I'd want to be able to carry it with me, so maybe a standard would be better.
Better yet, (since we're dreaming up stuff) I'd get one in a Leviatha size and another similar wyrm in the teacup size so I *would* have one I can carry with me but still have one with the glass eyes and the fancy colored tail.
And Tesla restrictions aside, that would take absolutely forever to breed to. I do have a red male and a long-eared mountain wyrm, so it's a start!
