Baldur's Gate meets Heroes of Might and Magic 3

Hey everyone,

In order to surpress any thoughts of my duties and distracting myself I started to create the swordcoast, that is the area of Baldur's Gate 1, as a map of Heroes of Might and Magic 3.

I'd like your opinion on this as well as some advice and thoughts if you'd like.
What is good, what is bad - what should be added?

What would you like to see in a certain areas and how should it be implemented?

At the moment I don't know how to emulate the sirens from the lighthouse area.
Should I use medusa or water elementals?

Here some pics of my work so far.
Please keep in mind that it's work in progress

Also there are a lot of things you just can't do because the HoMM3 Editor is limited in that regard of course.
This is just for fun anyway
