I am extremely difficult to satisfy with endings. Extremely.
I have been disappointed universally with Lord of the Rings, Hitch Hikers Guide, which in turn are some of my favourite books. So don't take this too personally.
I do really like what you've done with this. I like the direction you've taken it in. I just really dislike endings that aren't endings. This, if anything, is about 40 pages before the ending. :P
This is the main reason I don't write, I cannot write endings that satisfy myself.
