A: I don't currently accept commissions for maps.
A: The majority of artwork, maps and symbols/logos on this site are created and designed by myself, though I'd be lying if I said that I didn't use external assets to create some of them. This is why I don't try to make money out of some of my artwork, though if I was to in the future, I'd be sure to redesign the offending artwork from scratch at my own hand.
I also try to make sure that the assets I use are free to use, though I can't always find reliable sources that comply with this standard. As such if there is anyone out there who notice an asset I've used and it wasn't free to use, then I urgently ask to be notified of this, so I can rectify the issue.
A: I fully give permission to use my personal work for your personal campaigns, roleplay and general personal projects. This is assuming that your intentions are for non-commercial use. My personal work is not to be used in relation to anything commercial without my sole permission.
To an extent I also don't support the idea of using my personal work for your own world-building project or anything similar that shifts focus too far away from my personal work's original purpose.
You are allowed to share my personal work, and although it is not required, I would prefer to be credited. This also applies to when you wish to use my personal work for your personal projects, though it's not completely necessary to credit me for when you use my personal work in your campaigns.
I don't really find it necessary to ask me permission for anything non-commercial, though it is more or less up to you if you feel the need to do so.
A: In both cases you should send me an email describing to me as best you can what it is you have in mind, and preferably some information about your project and who you are (ie. details about your organization, company etc.). It might seem strange to say this, as it should be a given, but there are a surprising amount of people who are just terrible when it comes to this stuff. I should hope that you act professionally, as that will most likely increase the chances of me accepting your proposal.
Although having said that, much like my reasons for not doing commissions, it's very likely that I won't have the time to accept any invitations, though that might also change in the future.
