Life Drawing: More sketchy life-drawing..

So I'm on holiday! But that is no reason to get lackadaisical about doing anything creative, so I looked up a local life drawing class last night and had a bit of a scribble.
I only took some pencils and a small sketching book with me so that somewhat constrained me but I am posting a few drawings that I feel didn't turn out too badly.
We did many short sketches which as you will know are not my forte.. I think the first two here are maybe a five minute and ten minute and the last was three minutes.
