LEGO 6081 King's Mountain Fortress ADD-ON

I recently saw this set on craigslist selling for $100.00. No one was buying it, so the price went down to 90, 80, then 75. I figured out that spending $75 isn't too shabby since I thought this was a nice looking set, although I didn't feel the need to have it just yet, but definitely in the future. So I decided why not...
The castle has a big flaw in my view, so I had to improve upon it!
