Portrait Oil Painting

One of the focus of this year has been painting, and these paintings were done at Local Art school, uninstructed workshop(3 to 5 hours).
Black and White ones are self portrait,and were painted as homework for the painting class that I took early this year.

Since I`ve learned sculpture, I tried to achieve 3dimensional look, using value. I also tried to adjust the focus with value and edge control.
