One more thing I'd like to bring up for anybody willing to listen to my super picky self.
Today's lesson

On the left we have a good, high level of silhouette shift. Every ring has its own purpose that it fulfills, easily red and justified.
On the right we have what I consider to be a complete waste, while the green may contain some amount of silhouette shift the red and blue add a difference in lighting than that of the center ring which could have been easily extruded to the end of the red and then shifted to green.
My main point is that little tiny shifts in geometry really don't help the model, especially on something so low poly. Note though that this isn't a complaint about polygon count, rather that those tiny shifts take the lighting and change it just ever so slightly, distracting from other pieces with higher readings.
I like using words that make sense in my head but probably don't in anybody else's.
