Felix Dawkins from Oprhan Black

I had to draw this guy, he is just briliant.
Anyway I did it without reference and I also managed to keep it and do it in two layers only (the background is one).
It was really hard, first time doing something like this, so I am sharing for critics.
Done with Paint Tool Sai and some color adjustments in Photoshop.

The character belongs to Orphan Black TV series.
