Hey, I had another look - defenitely an awesome layout you produced here.

Some things:
- replace the GL ammo below the flag with the GL and place something else in mid; the GL is more of a defensive weapon
- replace the 50hp bubble at the PG with a 25hp bubble - you have too many of those IMO
- saw some stretched patch textures

Regarding your ideas:
I think the plans you have are alright, I have some alternative suggestions.
- I think moving MH to the place shown in the screenshot could work
- maybe move the TP exit down to the angled JP as shown in the pic; make sure you dont jump right onto the JP from the exit after using the tp if you deceide to implement this

General stuff for future projects:
- you used the texture set quite well in this map; now you could look into in stepping up with your brushdetail a little. You got quite a lot of straight walls in some areas, try to break them up while not blocking players in their movement abilities
- try move away from symmetric designs, it gives an illusion of more detail
- I don't know if you used ambient light in this map but I think your lighting could use a little more contrast; try to highlight cool elements of your architecture and create interesting shadows - keep the ambient light value around 2-5

Keep it up!

Thank you for your suggestions. I will keep them in mind for future maps.
