Nice progress! The text is really cool, looks pretty handwritten to me, though it could perhaps be faded a little, so it look like the ink has seeped into the paper a little. The easiest way to make the sigil look more hand-drawn would probably be to draw it by hand If you don't have a scanner or camera, I think it's perfectly fine as it is.

I still think there's too much emptiness to be honest, but I know you don't want to add more stuff, so I'd suggest to shrink the map instead. As far as I can see, there's no need for this size, everything would be legible and also look better if you resized the map to maybe 2/3 or even half the current size. It would be easier to get the overview and lessen the feel of emptiness. Some text might need to be enlarged a little, but most could probably stay as they are.
