I'm going to like it, looks good, textures are good, 6/10

UMMM... not a fan:
The green look weird. It is too monochromatic. Try using more color texture to add more variety to the map. As for lighting--these textures are normally used with brighter (almost fullbright) maps, i.e. justice. This is due to the cartoon feel that the textures give. Using a serious light scheme look quiet ironic.

Monochromatic is a theme, look the map sdm1 or sdm2.
