I think that the map is cool. I like that it's not the meta where people make a map that is just a wearhouse filled with crates. This map experiments with having the map take place in a cave wich you don't see a lot of. However I have some oppinions I would like to share.

My first problem is the size of the map. The saying is that size does not matter but i think that if it's to small it is not fun to play with. Jokes aside I think that the map could have another version where it is a 2v2 wingman map where A site is CT spawn, B site is T spawn and mid is the bomb site. The size is perfect for a wingman map and the layout would also work fine with no changes.

The only change I would suggest if the map became a wingman map with the spawns and the site being in the places i suggested is to make an opening here:

The second thing I think should be changed is the player models. I understand how you were thinking when you made both the T and CT models 2 different T models but it makes it confusing. The way you determine if the player you are looking at is a T or a CT is the playermodel. The models on this map makes you confused and some times when i played this map i shoot teammates when I was playing a CT or did not shoot an enemy because I thought it was an ally while playing as a T. Here i thing you should change the models to make the models fell less out of place.

That was my two main arguments. Except for those I think the map could look better by using more props or to make the mines feel les blocky, the map has no elevation changes at all wich if added could be good for gameplay (look at any official valve map as an example) and it feels od aesthetically in this case. You could do a loot of cool stuff with elevation changes when the map takes place in a cave. Have cool ladders that goes up to platforms that people used to stand on while mining for exapel.

This picture could be used as an example of a cool esthetic thing that could be in your map and an example of a littel but important elevation change with the stairs of that picture that could be used.

Hopefully these suggestions can be used as help to improve the map and good luck on the map in the future.
