Sleeping Beauty Level- New and Improved

Using the critique I received from my classsmates, I made some improvements to my level. 

1. I added a few doors, two of them locked, and a functional lock/key system. 
2. I added a bit of challenge to my level by requiring the player to backtrack to a previous era to find the key for one of the doors.
3. I made the pits lead to a basement that has no windows or doors, so it seems more natural.
4. I moved the skeletons to said basement, which is a more logical place to find the skeletons of dead people.
5. I built the lighting completely, making the lighting look more natural and even.
6. I fixed several of the gaps in the walls, ensuring the only light would come from the windows, torches, and the gaps in the partially-collapsed ceiling.

I have included screenshots so you may view my level.
