Played match on it with you yday, so i thought i would make this post with some review of the map.
Legend
High way = way you jump into from base using concrete ring
Long way = way you get into from base without any jumps (basically next to High way and lower)(had no idea how to call this, just went with sth)
HBD = way you can jump into from base, its right above spawn
main = connecting mid and stairs
Looks: Has nice feel to it, i think you got it pretty well. Still for example mid to highway speed looks kinda weird, but you said thats gonna be fixed in next beta.
Base: Flag seems pretty easily campable, which isnt really good. Altho its similar to pp1, the diference is that you dont need to look behind you when defending, while on pp1 you have to (given opponents are smart enough to go bd ^^). But i guess with proper teamwork it could actually work, there is plenty of ways how to grab so if you do it right you might be able to grab even if the defender is camping somewhere.
Mid: Works pretty well, many ways to outplay someone. Feels a little like xbamp1 with all the lines. Also as i already told you, High way is pretty OP imo, because there is no way to counter-play it if you dont go there. Imagine you go main and now you see/get recon that the enemy is comming to you from high way, you can either try to line, but thats probably not gonna work, or go back to base and wait for your opponent to do something. I feel like this isnt really good gameplay wise, what i said here makes High way safer compared to other ways. I have already given you some suggestions how to deal with it, just wanted it to be written, to see if other agree.
Tactics: As the map is right now, going main is disadvantage. If you go long way/high way you have the same lining opportunities plus you get much more freedom in terms of ways to take. Also, given that you go long way and you meet opponent there, he could just get away by running into HBD. I thought that adding some kind of BD connecting long way with HBD might be nice, also would add some complexity into gameplay, because you wouldnt have to take the path you chose, but you could change it pretty fast (you take the BD and can decide to take either main or long way to base)
To sum up:
I think you got down the theme really well, maybe that one clip brush(next to the crane) is disappointing and unnatural, also the speed mid > high way looks weird. Otherwise the map looks lovely, a lot of details and nicely done overall.
Looks == 8-9/10
Flow is pretty nice i think, its pretty fast paced, but i like that. I dont really know how to judge flow when there are walls with sharp corner, but i guess the main thing is, if anything sets you of your main curse, if you use jumps naturally and without much thinking.
Flow == 8/10
I really liked the way this map plays, given that you do something with HBD and maybe add the BD i suggested, i think that the gameplay is pretty much as good as it can get with the way you built the map.
