If you like my art enough to want to use it in a layout or such, please ASK. I will most probably say yes. On the other hand, using or archiving it without my permission will piss me off and make me angry with you. And if you like my art so much, why would you want me pissed off and angry with you?
Commission Art is out of bounds: no icons, nothing.
Feel free to friend me but don't be insulted if I don't friend you back. All my art posts are public so you'll be able to see those.
