Disk Arena

I made this disk arena in my minecraft, it's supposed to be looked upon in the Rezcraft/rezfix texture pack. Two teams, red and blue, fight each other with data disks. The lava is to prevent programs from jumping to the other side (the lava is three bricks wide, too wide for a jump). Programs come up where the cotton is, they need to break it and replace it before the actual match. There's a hole to the outside in the picture, I'm using that for construction and will be covered when I'm finished.
