tail designs for take

So! I've been searching for a thread for tail designs that people aren't using, and there fore allowing other mers to do so. I haven't, So, I figured I'd make one! if your like me, and make a ton of tail designs and never are going use them, feel free to post them here! I hope this end up being a great thread, but I don't know if you guys think so :/ I'll post a few of the ones I made and see if any body likes 'em! lets see what you guys come up with!Thanks!

This is a really cool idea! :)

I think there are already a few on here by artists, but here's my album.
