This is gonna be short and sweet. I get many, many, many requests asking for permission to use assets from my gallery. I don't have the time to respond to everyone, as much as I'd love to do so, so here I hope to answer any and all questions about my rules for using stuff. Fairly standard, so if you have any questions I don't answer here, please ask me in the comments.
1. Anyone can use anything in my gallery so long as they are modifying it or using it in a manner that makes it clear that one is not simply re-uploading my art unchanged.
2. My art can be used only if it is for NON-COMMERCIAL PURPOSES. If you plan to make a cent off of anything that involves using anything I've made and uploaded to my gallery, you must first contact me stating your intentions and asking my permission. This should be the only time that anyone should have to be asking to use my stuff, at least in a perfect world.
3. If one uses anything of mine, they must add a URL to the original source page in my gallery. If you upload it somewhere like DA, put the link in the author's notes. At the very least, have the credit "MoongazePonies" if you print or publish it where a URL wouldn't make sense.
I hope these three statements answer at least 99% of the questions I get daily about borrowing from my gallery, but if they don't, feel free to contact me. I have no problem answering questions, other than a severe lack of time - just be sure to make it clear in the header what the message is for.
I make most of the stuff in my gallery for people to use, I just ask for common courtesy when it is used. Thank you all for the support these past couple years, it's been lots of fun!
