Wow! you really did a lot to this since I've seen it last. you got the entire map colored, you made some changes to the PDF that really improve it. excellent job!
The only thing I'd personally like to see changed is to make the page margins narrower to really fill out the page. This would allow the maps to be bigger and the font to be larger and even easier to read.
Overall a good adventure that can be plopped down into almost any campaign with only a few hours of prep. It'd be good to keep in your back pocket as a DM if you should need it.
