If you've not come across these try I Write Like which states that it analyses word choice and writing style and compares the sample text against the great and the good. Now, I know I don't like to be pigeonholed, but...
Chapters 1 & 2 of Beneath The Shining Mountains was compared to the writing of Ursula K le Guin. [Er... right.]
Chapters 1 & 2 of Hostage of the Heart was compared to the writing of Gertrude Stein. [I'm speechless]
The Prologue of Torc of Moonlight was compared to the writing of Jack London, Chapter 1 to James Joyce. [James Joyce??]
A second opinion is needed here, methinks, so I tried inputting the Prologue and Chapter 1 of Torc of Moonlight into I Actually Write Like. The result?
"I actually write like someone about to go on a killing spree."
Now that I might believe. But I won't be sporting the accompanying dog turd on my blog, thank you. Not today, anyway. I'll just quit this displacement activity and get on with the writing.
