Simple, close cropped icons that have absolutely no textures. Different because normally, whenever I try a close crop, I end up thinking it looks awkward and zoom out. I'm also a texture whore who likes to put textures on just about everything.
Most importantly, I did not use Levels in these icons, which is beyond different for me. Working with Photoshop Elements, Levels has become my bread and butter and I use it in EVERY icon I make.....except these.
