With the current area I have started to use the coloring tool more. In my past areas I have used it but generally just adding grey shades to define the terrain. I have been experimenting with using much more colors on top of the terrain textures and I am quite happy with the depth it adds. Making mud look wet, trails from run off and just general muck. I am closing in on the end and I am still discovering new ways to do things. Playing this campaign it will be noticeable as I gained more confidence and abilities in area design and scripting. I have gone back a little to touch up here and there so it would be overly blatant as well as improving or just trashing and making all new scripts.
And the area progresses:
A gate to nowhere good.
