I like both the original and the revamped version of the map (Though I like the revamped version more). In the new version, you have a good, interesting layout that has plenty of platforms that can make for some cool firefights. But there's always room for improvement, so I'll just make a couple suggestions:
Platforms: Now, I don't intend on being a hypocrite and talking about how you could improve the basic layout of the map, I like it just the way it is, I'm talking about each platform
specifically. Most of the platforms you have are just rectangles! You don't really have to change
everything, but it'd be really cool if you just experiment with different shapes and see how it affects the gameplay and such (Not to mention it'd make the map all the more appealing and unique!).
Aesthetics: When it comes to lighting, you've got it practically spot-on. There we're only a couple areas I found to be oddly lit, which I've boxed in here:

As of right now its all just the standard BG (With some exceptions), but you could change it up a bit if you wanted. Change some area's into usurpation, or have the areas with water into the sewer BG, etc.
Water Pools: This one's just a personal opinion of mine that I'm suggesting. It has to do with the 2 pools at each end of the map. They're fine the way they are, but it'd be cool if you connected them somehow via an underground waterway. Like you could have a pool at the very middle, then some underground passage to each end. This one's just my opinion, since I think some water-based combat could do well in a map like this.
