You kind of gave this map the same name of a very popular dev map.

 

Just call it Heaven. I really love this map, I'll download your version !

 

Call it Oasis, or Utopia. Means the same thing.

 

FINALLY. I have been waiting for a good remake of Haven for so long. You sir, have made my day. Excellent.

 

I visited your map and... you really should work all the structure... Even if we can't see some part, it's obvious that's just blocks together. Create a Forunner structure and add more details inside the structure. A simple example : the circular hallway, you could add shield generator on the wall. It's a little pillar with white lines, it could be really cool and add some details.

For the rest, I let you work.

Good start, but you need to polish it with details.

 

I'll modify another map later today, maybe I'll go in Forge after to add some little things in your map and send it here to help you (if it's a good addition you'll be free to continue to forge from my version).

 

This actually doesn't look to bad at all. You could turn off light bake for any floor objects and walls that don't need to cast a global shadow and it will help a ton for your light budget and map.

Edit : Leave the floors a default texture with a gloss of like 4 or 5 and add the forerunner texture to the vertical walls and a bit of gloss variation in areas to give it a bit of life to the map.
