defense/ watch tower

IT APPEARS I'VE ONLY GOT 4 DOWNLOADS FOR THIS. I HONESTLY DON'T CARE ABOUT DOWNLOADS I MAKE THIS STUFF FOR YOUR ENJOYMENT. BUT COULD SOMEBODY POSSIBLY COMMENT TELLING ME WHAT WAS WRONG WITH IT SO I COULD MAKE IT EVEN BETTER OR POSSIBLY MAKE ANOTHER

this will be a defense/ watch tower for some kind of kingdom when its complete at the moment the upper floors are finished they include. two floors carrying pistons which will shove sand out of the tower and hopefully onto mobs one floor has 16 dispensers and another is a bedroom UPDATE: a position for archers has also been added and the bottom floor has been changed slightly. Also included is a strange sort of basement in which you wait for mobs to arrive (in that basement) so that you can kill them. While you're waiting for them to arrive there are 3 lower areas to wait in. Also added is a room which can have water poured out of it as a way of blocking people coming into your base

THE DOWNLOAD IS UP!
i have nothing against using this in a video just so long as you give me credit for this creation

-- if you find any strange redstone under the ground floor thats probably excess from a strange idea i had its nothing really
