Well I'm glad that you have motivation and I know what you're trying to do here. Bringing new aspects of gameplay into a map is fundamental in designing a map for use. However I just want you to consider this: There are two sides to designing a map, gameplay and realism. It's quite easy to get carried away by either (I've personally done it, I'm pretty sure every mapper has.)
But since this is PR, in terms of creating an interesting and exciting map you can take a little from the gameplay and make it more "realistic". Again I don't want to come across as a know it all and I don't want you to get offended by the remarks I make about your maps. But I see an issue with Brick and Mortar which mainly is that you've been so caught up in creating an interesting map with different gameplay aspects you have forgot about the realism aspects of it.
(Just going by the original photo) For example, the parking garage... would never actually be placed there. People know it's a parking garage. Why is half of it in the water?
A Peninsula that size wouldn't have any sizeable buildings on it like the hotel or high apartment building. Most of the buildings are too close to the water, they have no protection from sea tidal movement, waves, erosion etc. From a realistic engineering standpoint there has to be a rethink about the choice of buildings and placement.
I know from experience that creating a small peninsula is quite difficult to make it look just right. But I highly suggest going for a more "rural" setting if you want to keep that under developed feel to it.
As for the walls. I just don't get it. They are just kind of "there" and while I understand it breaks the peninsula fighting area up and stops long lines of sight there are many different and better ways of doing it than relying purely on statics.
Again this is mostly conjecture since I'm looking at one aerial photo. But you're intermingling too many different aspects together. Residential, industrial, religious. In an area that small there wouldn't be that many things and if there were they would be much more inconspicuous.
I suggest just making the peninsula bigger if you want to keep with the small urban centre idea. Raise it from the sea level more, but something with that shallow of a bank would not have that much development on it.
Or even try and do something like the Miami South Beach shoreline. Where there is built up area yes, but there is enough beach area between the built up buildings to provide that nice separation between water and engineering.
Another good example of peninsula design would honestly be BF3 rendition of Sharqi Peninsula. Here we can see the distance from the water that the building have. The sea wall that is in place against tidal movement and the raised elevation.
Also consider how peninsula's are naturally formed.
A peninsula is formed because water levels gradually rise due to a raise in temperatures. This occurs where the land is of low elevation.The rise in the water level leads to the land to be surrounded by water on only three sides, creating the peninsula.
This means that it's going to be much higher elevation than the water level. Because the peninsula at one point "was" a hill or top of a mountain. In the case of South Beach as mentioned above, it's an island which formed from silt deposit as opposed to erosion. Keep these things in mind while making something like this. While it doesn't necessarily go through the mind of the player, it will look gamey to them. Our eyes are extremely good at picking out things that just aren't "right".
Again I don't want to be "that guy" but I want you to try and rethink some of your plans for the area. From multiple viewing angles. It's not that I think what you're doing is bad, but I do want to stop you from pursuing your current direction. Pause. Take a break and just think about it. I don't want you to get too far into it and then realize that it isn't working out the way you envisioned it and then lose all resolve to continue it.
Just my two cents on the matter.
I'm really looking forward to seeing more photos of it though. So please do keep us updated
