Timothy Sahara Ryan Sketch

First successful Tim Ryan drawing I actually LIKE (the others are crap) and I must say for a sketch it's come out pretty well.  It's not much for now (I haven't been drawing aside from the odd doodle here and there these days...) but still.  This is also the first time I've actually successfully drawn a head from this angle!  The birds-eye-view jawline/facial features always mess me up!

Creative criticism is welcome, as usual.
