Tower of the Archmagi

First project I've ever uploaded on Planet Minecraft. I've decided that I should try and improve my building skill so this is just a quick something I whipped up in order to challenge my worst enemy, CIRCULAR TOWERS! I attempted to make a fantasy magicians tower out of cobblestone and a certain color wool. Nothing really too fancy about the terraforming except a few trees, been really busy and had no time to make anything fancy. The texture pack I used is the official Mithrintia Academy pack, You should head on over there to check it out. I hope you guys like it, throw in a diamond if you want! I would also love to hear your opinions and what I could improve on! :D Thanks in advanced.
