Of course, I'd love for you to!

Basically, reaching beyond web-comix. If you think your comics fit the pattern of Drawn & Quarterly, Fantagraphics, Alternative Press, Top Shelf and so on, you should submit here. That is, not genre specific, hopefully more idiosyncratic pieces. The borderline for my tastes and my definition of alternative comics is probably something like Oni Press or Heavy Metal.
As for quality, that's hard to say. It's case by case. Hopefully I see your effort in the piece.
The stuff I personally want to avoid for the time being are the things which I don't enjoy seeing so much, but also the things which overwhelm Deviant Art comic scenes:
1) Manga. There is good manga, but usually it is done in Japan. I've never seen any Western manga I've enjoyed.
2) Gag strips with the same pictures duplicated in each panel, maybe a little change, and obvious computer lettering. This is a real negative trend for web comics, and I'm dismayed by it.
3) Superheroes/100% pure genre work. This is hard, because I really enjoy some superhero comics, but they are too heavily synonymous with comics, especially in the States. And they are greatly over-represented in Deviant Arts comic groups. Pop culture riffs also fall into this category.
4) Furries. Too alternative for me.
5) Really unfinished stuff. For example, pencil sketches. Unless you'd print it and publish it as a finished pencil piece, this isn't a great place for that.
6) porn comics. There are better places for that than here. Everything in its right place.
7) Stuff being submitted to dozens and dozens of groups. Of course you want to promote yourself, but we also want you to be a member of this one and not simply use us without care to what the group's aims are.
8) Covers and standalone images that aren't comics (ask yourself 'is it sequential?' before submitting) though exceptions can be made for splash pages of regularly submitted comics.
9) Hate art (art discriminating against people based on gender, race, sexuality, disability, etc). Controversial themes are okay, discrimination is not. Should go without saying.
It seems negative to define the page by what it isn't, but that is one way to develop an identity.
When submitting, please submit to the category of you feel appropriate. If you feel the folder sections too constraining, feel free to recommend a new category here: alt-comix.deviantart.com/blog/…
