Post-Processing Practice (Patreon)

A while ago I had the rare chance to talk to Urbanator (Deviantart, Patreon, SFMLab) about post-processing. If you don't know him, he's an SFM artist that brings everything to the next level because of his attention to detail and a delicate, gorgeous smoothness in his work. I didn't have the chance to put anything into practice until very recently because of exams, so here's a tiny test.The main idea of the exercise is to remove out of place pixels and horrendously jagged edges (which SFM is famous for), as well as soften lighting and texture.
