These are the first models that I have marked forward arc on. I hadn't done so on models in the past because I just didn't care for the way it looked. I thought and read a bunch on different ways to do it that would be subtle and not take away from the model. I ended up thinking that maybe just a thin line of gloss over the flat finish of the rest of the base would be noticeable only if you were looking for it. It turned out well and is just noticeable enough to be useful but without standing out.
