Gioiella, a small Serpentine City map

My current work in progress:
This is basically going to be a fantasy version of Venice, hugely affected by pacts with faery lords / fey in general.
Thanks a lot to the creators of this style. It's very easy to use and I have not faced any issues apart from one very minor case of transparency acne.
I'm currently planning to add more piers and boats. I might also add another island with shipbuilding facilities (even with magic, it's pretty hard to operate a maritime city without your own boats...).
Also trying out different layout options: Might use a different banner colour, but moving the city to the right looks good - leaves more room for Explanations and annotations on the left side.
I've also created a draft "fey activity heat map" to keep track of my thoughts in that regard.
What do you think about it so far?
Comments
Can't read fey, so I'm presuming those are the different fey factions. However, nice idea, and I'm presuming you did that within the same physical map using sheets you can activate and deactivate.
@Bidmaron
The overlay colours do not show different factions, but the general level of fey activity, going from red (always, plenty) to green (very little) and clear (no fey). Since the shown sheet was just a quick draft, I was writing the notes in German.
I created the heat map using basic image processing / paint software, but I'm considering using overlays to the original map for the final version.
Is there any way to apply a desaturation filter to an entire map, besides adding an "adjust hue/saturation" effect to every sheet?
The effects dialog have a set of radio buttons to switch between whole map effects and individual sheets.
Had a rather productive Easter Monday:
Added the shipyards and another residential island.
The close proximity to the "important small pact island" (no. 14) gave me the idea for another storyline, and so I've also added a bit of an open air dungeon (no. 13).
Played around with the global map effects switch a bit (Thanks again Monsen), but still on the fence whether I should include the overlays in the Source map.
Then I added the Buttons, Parchment background and cartouches. Enough work for today. The only thing i might still add is some Island / large channel names. I'm a bit tempted to ask my players if they have some time this evening...
Wonderful city. I hope you would consider adding it to the Atlas somewhere.
Any coastal city should do.
Wow, really cool!
Very very beautiful!
