For some reason PM emails haven't been coming through so I've missed messages in the past. There's no need to contact me for permission to use my art, though notification is appreciated.
I understand that licensing can often be problematic, even with the great advancements that have been made in the past years. As such, if you run into any problems with the licenses specified on my work, drop me an email and we can hash out individual permissions to make sure that you can use the resources smoothly and without issue.
Regrettably I am currently closed to new commissions, thanks to the rigors of graduate school. Feel free to contact me though.
