I am not an artist in my real life and will be busy working in the foreseeable future. So I won't do requests, trades or commissions.
Some of my deviations are released under the WTFPL, which means you can just do whatever you want to with them.
You can check my deviation' description to find whether it is under the WTFPL or not.
Pity that DeviantART doesn't have an official way to show this authorization.
