When I was making this I didn't consider the sclae of the Gate of Erebor to the size of the Lonely Mountain, so in the end tthe size of the gate had to be made smaller. Also, that large body of water is meant to be a little river (I obviously need to reconsider the size of the river.) Thank you for the suggestions!

Thanks; the reason they are only green is due to when I was looking at pictures of Erebor, it always seemed to be a sort of green; I couldn't really find a suitable green, so I just used the combination of those two greens.

Right now I'm working on the entrance to Erebor, and by my progress so far, a simple version of the map may be downloadable within this week.
