I'd say go ahead, I'm pretty sure there's nothing in the dreaded AUP against it.

Well I certainly hope there isn't! Although the submission categories are atrocious enough to almost make you think so (seriously though, there's no category for sculpture or jewellery! I feel for all the furry artists who make those kinds of art!)

Off-hand, I'm not sure if there's even an "Other" category.

There's "Misc". Not a bad category to have, but I feel there's too many good things than end up there and go unlooked at because whomever was responsible for the categories never envisioned such simple things as jewellery, sculpture or Fantasy Anthro, Sci-fi-Anthro, Western or Steampunk Anthro, Macabre Anthro... Honestly, FA rewards fetish artists first (there's two giant categories for them, one clean one not, both the same otherwise), then ironically the next whom are rewarded are NON-anthro artists (everything else is basically non-anthro) and ironically, the people who draw the bread and butter of Furry art are shafted with just TWO options: General Furry art Tame, or General Furry art Mature. It's no wonder lots of people see FA as little more than a furry porn site!

That's true, FA is not very well laid out. There are lots of things that could be better, categories not least among them. What's worse is that 'Neer et al aren't doing anything about it.
