Thanks a bunch for all the feedback, it's very helpful and much appreciated!

I begun drawing some forest following the first design, and here is the result. To me, they feel a little to "sloppy" and the lines feel too thick. However, with a little more detailing, they will do.
I also added a design of a smaller wall/beginning of establishment that will be a Mining Industry/colony in the bottom left corner. Perhaps that will help making the scale more clear.

Ps/ After adding color to some doodles in PS over lunch ( uploaded them in a album on my profile) I couldn't hesitate to give this a quick touch as well. Just to see how it could look.
