Since the initial preview, I've made the following changes:

 

All new custom Worldspawn

New skybox

All new custom vision & fog

Finished off-map scenery & playable area

Detailed the cave

Placed grass over about 85% of the playable area

Replaced nearly all case (placeholder) textures

Imported a few models and textures from Black Ops

Currently the misc_model count is 5,688, I wouldn't expect the final count to exceed 8,000, which is lower than most of my levels.
