Another concept for a map that didn't make it, but this was one of the first ones that I remember stretching the canvas from my original drawing to change the composition. The whole right third was added later in Photoshop, because I wanted to show where the bridge led to. By this time I'd learned to start making custom leaf brushes to quickly create jungle foliage.
Slightly older sketch where I was trying to show a bit of the diversity of color in what some of the buildings in an old Mexican town might have, along with some of the stuff you'd find on the streets that help instill life into it, without actually having to put people in.
Normal turnaround time on concepts like these are 1-2 days.
