Aris - Thanks for posting. Nice work.
Colors look quite nice. Also the icons work well too. Overall very easy to look at.
A few suggestions would be:
- Road color coding scheme is not intuitive to me. Even with legend to connect it to, I would add casings and use a ramped color or just two complimentary colors.
- Possible check some of the type - its your call - but you might add casings to type where it overlaps feature.
- Faux bathymetry
Do you have access to the real thing? Keep it vector (convert or simplify & trace) or use VMAP0 contours. Since you are describing terrain contours,
I would make an effort to show actual sea contour (as a lesser overall effect of course).
What is the name of the font?
