the lighting is bland, the tincturing is repetitive, and the architecture is OK.(not good)

"the map consist of 3 leveled platforms, dirt metal and steel."

u know steel is a metal to? :P

There are a lot of things that are wrong with this map.

*The layout creates racetrack like conditions for gameplay. Since all the good weapons are on the edge of the map and because the overall shape of the map is square, players can just run around the perimeter with rockets and 150 health, killing other players as they respawn.

*I feel like a broken record here, but the map is very ugly and bland, the color palette is almost entirely shades of brown.

*The texturing is repetitive. For example, the entire exterior of the building is the same texture. Try using a greater variety of textures to add visual details to surfaces or to make geometric details stand out. And in reference to my earlier comment, try using a more varied color palette.
