Interesting map for a first time. I've got to admit; it's a pretty original theme.

As it's you're first map, I can't blame you not knowing how to package content properly. That's why I would advice to read the Packaging Guide.

Is this map made in another release than collect edition, or are those flames near the waterfalls intentionally placed?

Perhaps you could have used some more textures than just 1; as it's quite confusing now when navigating through the map. This might be your intention, but isn't great for the flow and gameplay.

Seems like you're more into instagib? Please still provide a proper item placement instead of just bulking some riflerounds near the middle of the map.

The lighting could contain a little more ambient; it feels too dark to actually where you are going to when moving around in certain places.

Please be sure to read the Flow and Layout Guide.

Anyway, nice attempt for a first time!

You have some nice details, and your theme is pretty clear. I don't see is being that good as a serious map right now though.
