3 pieces from my old sketchbook

I found some old drawings that I made in my old sketchbook that i somewhat kind of like. I tried out different media such as watercolor and a little bit with oil pastel. 

First Image: All done in watercolor. I tried to give it a special effect by painting the face in a odd color to make it more dynamic.

Second image: I experimented by adding lots of water with the watercolors to get that type of effect. I also used a black marker for this illustration.

Third Image: As I am not used to using oil pastel and I may say it is not one of favorite type of media I gave it a try. In this one I decided to do the illustration by using the same color.
