Character portrait made with Maya / Zbrush / Photoshop. Workflow was 5minute boxmodel in Maya, sculpt in Zbrush, retopo in Zbrush, UVs in UVlayout, detail in Zbrush, light/render with Maya/Mental Ray, composite in Photoshop. I then shot photos of smoke specifically for this image that were then composited... so no, not Maya Fluids. Wish I had that kind of time... heh.
