These are geometrical portraits are great! Nice balance of clean lines and organic details. 

Thank you.

I love this.  Your style is reall cool.

These read amazingly from a distance, the expression is quite intense and the vertical lines used for dithering accentuate the face to increase that intensity. The brow details feel perhaps a bit too regular in comparison to the more dynamic sizing of all the other features, but other than that digging the style Hadoc!
