Well, the map looks good, there are some nice brush works and it's great to increase layout designing habilities.
The map has many areas, and that does not allow to play with a small group of people, as you would die and wouldn't even notice from where the bullet came.
This map is great in every way but I wouldn't advise to play on it with a small group since it's so big but, it makes an intense battle field with lots of places to hide keeping the game intense at all times. The look and game play are both great. I really like your work.
