The short version:
-Main character Willow is a knock off of the main character look wise from the Last Unicorn, a raging Mary Sue with no flaws who's always the "poor me!" victim and the center of the world and is downright annoying as she flops back and forth between being able to fight for herself (http://earthsongsaga.com/vol2/85.html) and being a wimp (http://earthsongsaga.com/vol2/87.html).
-Example of how annoying Willow is; Emo Vampire tells his sob story, but she's better because she's the center of the story and would "never" do anything bad like Emo Vamp did, even if she didn't have a choice: http://earthsongsaga.com/vol2/114.html
-Willow is the center of the universe, and it pains the main caretaker of these pathetic mythological beings to loose her more than anyone else because only Willow matters: http://earthsongsaga.com/vol3/8.html
-Story is a poorly conceived excuse to throw every mythological creature out there into one big disgusting orgy pile.
The chapter that poorly explains it all: http://earthsongsaga.com/vol1/ch3cover.html
-All of the characters are cliche and annoying as all hell:
Dragon lady plays the cliche annoying, upbeat character(make her shut up, ugh): http://earthsongsaga.com/vol2/20.html
Fairy chick plays the small, scrappy character who's always willing to get in a fight over the dumbest things: http://earthsongsaga.com/vol2/35.html
Elf woman plays the emotionally closed off, cold hearted bitch: http://earthsongsaga.com/vol2/47.html
And what cliche cast of heroes would be without a cliche Japanese, stoic fighter? Not this one: http://earthsongsaga.com/vol1/25.html http://earthsongsaga.com/vol1/107.html
And this is only the part of the horrible main cast, just check out the villains.
Artist is also quite ungrateful. She's gotten her readers to pay for her trips to conventions a couple times now and the coup de gras was when her old computer and photoshop died, within less than a week her readers paid for her brand spankin' new computer and photoshop and in return she was supposed to give them extra updates a week, but instead she barely gave them 2 updates before claiming she was too busy to give them extra updates and she'll give them to her readers a later date. That's a great way to say you're grateful to your readers for buying you a whole new computer and Photoshop.
