They do look better now, agreed. I still think that they do not look really like trees...but it is still obvious what they symbolize so i guess that is all that matters (and it's just my opinion anyway ).
As for the mountains...i see, all handdrawn...wow. Very nice work...and i guess a lot of work If you're willing, i'd really like to have those mountains in a brush-version.

Looking forward to seeing this map develop further.
Oh and btw, is there more of this world mapped out (even if it's only in your head)? Or was this just a "ok, let's do a random map, for fun" ?
