The middle one is Mamis "melting icecream" design recreated by Deviantart user BramStark. I added a background layer.
The one at the front is an alternative design from Deviantart user yoruichi228, I added the background layer.
The one at the back is my own creation called "melting paint", I used PS brushes from Deviantart users minnie-brushes, Ch4ron and Axeraider70 to make it.
I will change it up soon, I will probably keep the original Mami design one though.
If you have any suggestions on what I could add/replace please let me hear them.
Here are the designs I used:
I also have a full set of these left over that I don't need (6 individual stickers).
