Over the last years I learned and received so much from the Free Software/OpenSource philosophy and community.
I work only with free/open source software like GIMP, Krita, Blender, MyPaint, Inkscape and more, have learned a lot from tutorials published under the Creative Commons License (e.g. through David Revoy's site), and my computers have been running GNU/Linux for ages.
As a result I feel the need to give something back to this fantastic community of creators, and so I release all my work on this website www.acrazymind.com under the Creative Commons Attribution-ShareAlike 4.0 International License. This means you may share and redistribute my work in any medium or format, as well as remix, transform, and build upon the material for any purpose, including commercial ones - as long as you credit me (acrazymind) as the original author and release your work under this same license. If you do, I'd love to hear about your project!
I believe it's important to show that sharing and collaboration are incredibly valuable in any field of human endeavour, that we can reach much greater heights by building upon each other's achievements rather than tearing one another down in petty fights over intellectual property.
Excluded from this are of course characters or other intellectual properties of any third party that I may create some sort of fanart of - they are the sole property of their respective owners and using them in a commercial manner usually requires written permission. Regarding commissions my client and I will negotiate usage rights on an individual case to case basis, depending on their needs.
