There is so much detail to these faces that one can't help zooming in to study each in detail. This shows expert use of the palette. One of the things I like most is how the colors blend even at high levels of zooming, unfortunately that is not conveyed in the preview (not sure why) and I almost did not click on it, glad I did though. Thanks for sharing this.
Haha, these are great. Each one is wonderfully expressive.
reminds me a lot of Papers Please. nice job
