....Beware, they HAVE to be exactly 100x100 pixels!
We can no longer use icons that are 50x50 pixels. I tested it out by using one icon I made of that size and I can't change it to a 50x50 icon. So in the future I will now have to take icon commissions that's 100x100 pixels. But I can still make the original size for other things if you like too.
Just want to let everyone know. I'll be changing my icon soon anyhow. Don't plan to keep Yumi as my icon for very long, hehe.
