MAJOR PROJECT! Part 2 of Lab - Security

I built some awesome redstone security into my lab. The outside looks great now, and the inside has some new addons to it that I'm giving you a sneak peak of ;)
First is a overview of the redstone. Heres the redstone security in order:

1. Color-Combination Doors

2. Lever-Combination Door

3. Laser Door

4. Key card Activated Door

And heres the sneak-peak :)

 

I worked really hard on the redstone, I hope you guys liked it

 

The interior of it looks really nice. Good job!!
