Design exchange - Exchange unwanted adopts by me

Since I can't find the other journal for this I'll just make a new one;
The premise is simple!
I will put thumbnails to my designs/adopts that I particularly like.
If you own one of these designs and no longer want them, you can give them back to me in exchange for art by me, or adopt tickets.
Art will be close or equal in value to what you bought the adopt for/added value for commissioned art(not gift art)
But what are adopt tickets you say? Allow me to explain.
Say you adopted a pony off me, and you bought it for 400/$4, but no longer want it. You will get a ticket from me equal in value to $4/400(or higher if there is commissioned art, not gift art), and you can use it to get one or more adopts priced at that amount for free in the future. You can use it on an auction, adding onto what money you have, or just by itself. You can also use it for 2 $2/200 adopts, or just one $4/400 adopt! And I get your unwanted design back. ^^
There may be adopt sets where I specify that tickets may not be used, but do not worry! I will only do this if I really like the design or if I'm in dire need of money. I have a private sta.sh document so that I remember everyone who has tickets, so don't worry about proving that you have them!
Simple enough, yes? ouo

So, without further adieu, here are the thumbs for what designs I am willing to offer these things for!
