This weekend I came across the portfolio of Brazilian artist Cristiano Siqueira (a.k.a. CrisVector).  All of his pieces are vector based digital artwork.  His main creation tool is Illustrator; using reference pictures, hand sketches or Poser images as underlays.  What I really like about Cris' work is his bold use of color, and the interesting place where most of his work exists (especially the Women series) somewhere between realism and comic.
