This is my first attempt at mapping. I thought I would do something small, and this is what came to my mind. When the military and police s.w.a.t. teams train for CQB (close quarters battle) they use what's called a tirehouse, basically old tires stacked up about 10 ft high and filled with dirt. I could not find a suitable tire texture so I used concrete and plywood. I can not get the plywood to look right so if anyone has any ideas on it let me know. I would like some feedback on what you all think, positive or negative.
