1. The ship symbols, I like the use of scale, but not so sure on the shape and color. I would tend to associate a brownish color to tall ship.
2. I like the bubbles, (e.g. Valberg tower) but I would consider making the outline a little darker,
3. Also not sure what the symbols within the bubbles mean.
4. The fountain like symbol on top of BREIAVTNET ????
5. Creating a uniform symbol set for any map can be hard (actually it is hard). Maybe a bit of room for improvement on that issue. E.g. why is the post office symbol bigger and red. Is it more important then the press and media center?

Hello Jacques and thank you for taking your time to comment, very much appreciated.
Yes, all valid points taken. Some under my control, some unfortunately not, but all valid and food for thought.
Feedback is the Breakfast of Champions.
The logo/client dictates the blue ships

Bubbles outline, yes, have been tweaking for a while (symbols; legend on accompanying City Map)
Yes, 'Post Office' very very important for Crew & Captain; they all run to send Postcards home to Mum!
Palette took a few years; still working on symbols, as you say 'not an easy task'
Breiavatnet; the Municipality wanted to drain it and build a Car Park a few years back. The symbol tells them "Keep you're greedy hands off!"
Thank you once again, take care and good luck with all your projects Jacques.
Best wishes,
Kevin-Paul
