I like your trees, but they looks better on the right (near ambrose tears) than the left (nightveil woods) imho. Did you do something different?
For me, your cities (very well done!) labels are legible. I have more trouble to read the labels on a few mountains and seas actually (like "waters of malice" and "hills of the uninvinted"). Maybe you could try a slight glow under the labels?
And yes, you have to color that sea dragon or Jalyha will be the one of the rare to spot it (plus, I'm sure it will be great when colored).
That's what you have to do in order to be able to change/fix things! I keep layers separated to the end and merged just for print. Sadly, my software tend to force me to merge some or the file may come to big for it.By Seredemia
I haven't merged any layers at all
That's already an amazing map, anyhow.
