I love Guilherme Kramer’s work. He was the first artist to actually stick in my culturally ignorant mind and his pictures inspired my biggest (and still growing) tattoo. Even my own idle attempts at drawing were triggered by a desire to match his stuff, although hopefully I’ve moved on a bit from mimicry since then.
I love the freedom of his work, the strangeness, the intricacy, the weight it all holds despite the seeming lack of carefully planned force. So, as an introduction, here are a few randomly picked pieces of his to have a glance at. You can find more of his work here in far higher quality.
