I've decided to open commissions on Deviant Art in addition to the Pixiv option. Due to the rules on DA being a bit of a hassle, NSFW in general is not allowed. Ask me if you're unsure.

It appears I can post as many commission options as I want, so if there's something you want specifically that isn't covered in the options, DM me on DA (please include in the subject it's commission related otherwise I might gloss over it; I get a lot of spam/free request DMs).
