Cartographic decisions for dissertation

So now I've (almost) finished writing my dissertation, I'm putting in the various figures. I'm mainly using QGIS for this, most of the time the map composition feels more intuitive than ArcMap.
My previous post showed a three colour composite of showing image (or an aspect layer), elevation and slope, but I think that can be difficult to interpret, becasue a steep slope would either be blue, cyan, or magenta or white depending on what else is in the other layers.
So I'll be doing pseudocolour like this, using an image layer underlaid using transparency. I'm using meters in an Equicylindrical projection with 40 degrees latitude parallel. I think its nice to have metres as units for figures of individual objects/tiles, but maybe lat/long would work better for larger summary plots?
