Nice flow and the render blends well. The light on his face seems a bit random though as there is no light source.
Although I don't like the render, since he looks kinda chubby, you really did manage to make something nice. The flow is nice, the effects are nice, but you do miss a lightsource of some kind. Also, if I were you, I would have used a bit more blur and sharpen to create a good focal point. But really, it's nice.
Yup, I love the flow and colors. Could darken the sides so that it focuses on the Focal and flow. Nice fx. KIU!
