Some of you might have seen me on GG2, I'm a fairly new member. Just recently I watched Vaati's (very, very helpful, thank you so much) video tutorial for CTF maps and figured I'd try my hand at making one. I am quite pleased with the results, but being inexperienced, I don't quite know which features might be considered good or bad. I would simply like some more seasoned members to give me some constructive criticism, because I really need that. Anyways, without further ado, my map, "GENERATORS" (the image might not show up, I don't quite know how the HTML works)

I like it, but some problem spots I think may come up are:
- The underground "green" area might be too long and narrow. Although there is an upper walkway in the green halls, rocketspamming is probably imminent in that green area no matter what I do.
- The Red and Blu bases are too "enclosed." I'm thinking that Infiltrators won't have much room to hide. Also, Runners might die too quickly once they enter the enemy base. However, I added multiple paths to offset this as much as possible.
- The "unique" drop-in spawn might not be in the right position. Respawn room placement is something that I can't quite predict.
Now, I really had no actual story behind this map. I figured that it would be cool enough to have huge electrical generators in an underground network that fuel the race between Red and Blu for world domination. How? Next to Red and Blu's spawn stands a 20-foot tall incinerator laser (similar to that of the familiar Death Star).
Anyways, your help is appreciated. The png image above is already embedded with the WM, BG, spawns, med cabinets, spawn doors, and all that good stuff. Thanks for your help!!
EDIT: I accidentally resized the image, so the new, un-resized version is posted in place of the original.EDIT #2: Okay, I replaced original underground green "hallways" with a new portion of staircases and such. Thanks for all the suggestions and I hope you enjoy my map!
