Blind contour drawing and a portrait

Today was quite an amusing day as we did a lot of blind contour drawing, wich basically means "Do not look at the paper!". Drawing while not knowing what exactly your drawing looks like a rather difficult, but a lot of fun :) For some reason my hands won't keep up with my mind so I made a bunch of 'interesting' sketches of my classmates:

Later we paired up and made portraits. I had the honor of drawing Jona and despite some obvious mistakes i think it's okay, considering that I've never really made a portrait before ;) I'm learning as I go >^.^<
