Spock and Kirk

I fell in love with Star Trek, and I decided to practice another way to color a picture with a simple drawing of Mr. Spock and James T.Kirk. I based on the actors of new films, but I didn't try to draw realistic portraits of the actor, despite on, Kirks seems him a bit! xD, I drawed this characters in my style.
I made this grisaille with SAI and Photoshop. It's a bit strange, but I enjoyed painting this.
I hope you like! ^^
