Hi I'm sqbr@ao3.org, creator of fanfic, fanart, and the odd fan game for a variety of fandoms. I also have a bunch of fanart not posted to the AO3 which I broadly outline here. Here's my permission statement.

Some notable fandoms: Avatar the Last Airbender, Portal, Dragon Age, Mass Effect, Hakuoki, Pride and Prejudice

Also I have some fanart for Grandmaster of Demonic Cultivation.

The tone is usually fairly light and humourous, but some have angst/violence etc. There's a mix of gen and all sorts of romance, including polyamorous, and a few works with non-binary characters.
