Sketches - Face #12 & 13

I have been practicing sketching faces...just small pieces of paper that are handy...trying to get the eyes right...the chin...the nose...the lips...the angle. The lower one of these sketches...I'm happy with the jaw line and angle... The top of the two sketches...I like the nose and the lips...still not sure about the eyes... I'm enjoying the 29 Faces Challenge...it is definitely challenging. I've never considered myself a technically good artist...I love colours and more abstract types of art rather than more detailed art. This is pushing me into uncharted waters...
