Stadium

This is a creative project of a stadium that i will do in my friend's server.
Is a basketball stadium intirely invented by me, the smaller circle is where the seats are and the larger circle is the main entrance (with diamond floor, not too cheap!) the main length is of 53 blocks, the smaller circle is 40 blocks. the roof will be made of ice, the walls of ice and quarz.
this was my first blog but i don't have already a computer (writing with the mac) so don't be too bad with me :)
Hope you enjoy.
-( i made a redstone circuit for points and fixed the smaller circle, top left was wrong)
thx for diamonds!
