Any time! I’m a graphic nerd with none of the book learning, but I do work at a screen printing shop, so I have some intuitive understanding of logo/icon design, but don’t have the theory to go with it.
In other words, I have wildly subjective opinions that I’ll randomly dig my heels in on. (Sometimes when I have no idea what I’m talking about ha!)
Take these icons, add one more layer of simple gradient shading: perfection
For example, GIMP’s icon looks especially bad here to me. If it had just a hint of black shading, it would look massively better (imho).
