Barracks Full Metal Jacket Cin4d

This is a miltary type of barracks. This is my 4th structure I have made in C4d modeling.Similar looking to a cartridge bullet. Based also on the style of Renegade. After making this I find a lot mistakes and flaws and get more ideas, My apologies for the blurred render.I keep having issues.
I am training myself to learn this.I did with just a few of the tools I have learned.
Creator is Queenhunter.

This model includes: 3 cylinders,4 B splines,3 planes, 1 capsule and mainly just using knife and extrude.
