You can see which characters are up for offer in this forum thread.

Hello, apologies for lack of activity over the past year. I have been caught up in my studies and haven't been able to dedicate as much time as I would have liked to the character design community anymore. As a result, I have decided to start cutting down on the number of characters I own, as I don't think I am able to give them a good home.

I am still going to hold onto many of the characters as I still draw them every now and then for stress relief, but many will be given up for trade.

I love all of the characters and I admire all of the amazingly talented artists and designers who put their effort into making the characters, but I am sure someone else would be able to make better use of them right now.

I haven't had much time to draw my characters recently, so I will be taking money and art offers on certain characters. Folders and updates to come. Sorry for inactivity - Gray
