Male Face Practice

I tried to practice some male faces this week, but while I intended to do a bunch of sketches I kinda ended up just spending more and more time on this one, so... yeah, I thought I might as well share it with you guys, after spending wayyy to much time on it
Hope anybody likes it!
Sorry for the sketchiness, but as I said, it was supposed to be just a little sketch, so I didn't really care too much about the end result

So, basically what I did here was trying to achieve a likeness by doing iterations of the left face. I thought about it as younger brother (left), father (middle) and older brother (right), I am not sure if it was really successful though.

[Edit: June 2016] Worked a little bit more on it, I really felt like adding some freckles to the younger brother :3
