Best places for webcomics/online graphic novels?

[comicbookquestion]

I am sorry if this is the wrong place for the question, but I am stuck as to where to put it!

I am the carer for my daughter (19yo) who is obsessed with reading Graphic Novels (she has a huge collection including the classics such V for Vendetta, Watchmen etc) and I am struggling to find new material for her to read

She generally prefers longer series, but i would appreciate any suggestions

Has she tried Scary Go Round? It's literally the best.

Also Gunnerkrigg Court is pretty good.

She might also like Stand Still. Stay Silent It's a post-apocalyptic series set in Scandinavia and is ongoing - the artist is up to page 718 at the moment. She's also done another webcomic called A Redtail's Dream, which I haven't read much of, but also seems very good. There are scary and dramatic bits in both, but they're also funny and observant.
