Morning Dom 
I’ve actually just switched from your blog. Feel free to quote away. 
The agent of a fellow Scriv crew member and his partner/collaborator, advised them to write their novels as screenplays, first. The topic has been covered in the forums. The positive impact of the exercise on the novel itself, is supposed to be really worthwhile. This gal ‘n’ guy combo, are a formidable combo of published authors, so when they (he), proffer(s), their agent’s advice, to the rest of the crew, you can take it as read, that it’s advice they’ve evaluated, and embraced themselves. So, it may be worth your while checking out the concept. 
As far as critiquing, Regarding Avalon,goes, I’m afraid I’m not skilled in that area. I only know what I like. If I’m not, aware, that I’m engaged in the reading process, then I’m enjoying the experience very much. I use the word, enjoying, to cover a multitude of emotional responses. I was definitely, not, aware I was reading, Regarding Avalon. The only negative emotion I experienced, was a tinge of disappointment at finishing the book.
Now! Notwithstanding the above reference to, screenplays, I was inferring, in my earlier post, that, as it stands, the novel, Regarding Avalon, would make, not just a great movie, but a movie that transcends demarcated genre boundaries. Obviously, it wouldn’t work as such, if it was made purely as a, lovefestic, paean to computer generated imagery/game/roll playing/shoot em upery. In fact, I wouldn’t use CGI at all. I’d use real locations and make real actors resemble our percived notions of avatars. Now that would be kinky!! 
Anyway, Dom, I read the book at every available opportunity throughout the days and at bedtimes. Gripping! There are best selling novels out there, that I wouldn’t say that about, and…there are some big budget movies too, whose budgets would’ve been better utilised, making/filming, Regarding Avalon.
Best wind up now, lest folk think I’m your avatar giving you a plug!!

Take care
Vic
P.S. one little nitpick, give us a PM
