I get a lot of people who ask me various questions about usage of my art- Here is my stance on the matter. I really don't mind if you want to use any of my pictures (unless they are commissions, which are labeled).
This includes use as signatures, avatars, original stories, etc., as long as you credit and link back, and as long as you don't intend to make any profit from the use of my artwork.
I also don't mind if you want to use any of my pictures as references for drawing/redrawing (although you can probably find much better work out there to reference ), and if I have any sketches or line arts up at any point, you can color them as you please. You don't need to ask my permission for any of these things, but I would like a link (you can even just post it here in the comments section) so I can see how/where you are using my work
I know I don't see all the notes that I get, and I try to make sure I read all my comments but rarely get to respond back to them, but I always feel bad when I see one of these requests several weeks after it was made and appreciate the politeness in asking. From now on, you don't have to worry about getting my written permission, since I'm giving it to you here Just please respect the boundaries I have set, especially since I don't think they are strict or unreasonable at all.
Hope you are all having a great day
