Rennisances sketches/Drawings

[Renaissance]

(sorry, it should say OT somewere in the title)
Ok, just to tell everyone: I Really Can't Draw anything living, (trees, humans, lions, etc.)
BUT I Can Draw Building Relatively good.
Below are my two latest drawings, i work Sorta hard on this, doing them mainly at school: (note: i use a Scanner to upload the files to my computer, they look better in real life.)
1. A Battering ram Attacking a castle wall.
2.A Point of view shot of a guy staring up at a castle.
Hope you like!
