LOL!!! Nooo don't compare me to him; his writing is so bad >.>
Honestly 5000 words is not a lot. Not for, say, a 20-chapter fic. And, again, it's not the length but the quality of your content that will turn readers away. Plus, you know... you should never write for the readers. Write for yourself
Write a story you enjoy, and other people will enjoy it, too. I posted my original fic with those loooong chapters
on fictionpress.net (sister site to fanfiction.net) and have 74 reviews and 156 faves, and this is from people randomly finding the fic using tags (so it's not like I had a ready fanbase). Which is not to brag "Oh ho ho my writing is so fancy and brings all the readers to my yard" but just to say that my long chapters never hurt me.
I love Game of Thrones, lol! Well more so the show than the books*now watch as I be smited by 3 million people*, but I like his characters and the world.
FP.net? What is that place like? I have only been on FF.net, and Quotev.
Well then I hope to have your luck once my chapters truly start to get long!
Oh, my, you're setting yourself an interesting challenge! I look forward to reading this.
CuriousArtemis is probably a better person for advice on this, but the best judge of whether it's the right length is whether it's conveying what you want it to. My background as a copy editor tends to make me pare words to get the most effect with the fewest words, which isn't necessarily good for fiction either.
I read quite a few stories that switch between characters so I am used to reading it, just not writing it. We'll see how it goes.
I'll take advice from anyone who seems to be capable! There are a lot of people in this thread that I think are amazing writers so it's kind of intimidating, lol.
