Neat and really nice.
Definitely love the style.

The only things that bothers me (just a bit, don't be mad at me) are:
- The small lake, right under "Kellespau". It sticks out. It doesn't reflect the isometric style and attracts the eye too much. Varying the thickness of the line would suffice I guess.
It's ok with the rivers and the coasts but the lake may be changed a little bit.

- Where is the river that fills up this lake?
We've got plenty of rivers west of the mountains but nothing East. Looks unbalanced to me.

Just my 2 cents.
I do love the map and wish I could do the same :/
