Drawing exercises

Here are some sketches I did earlier, a bit of watercolor practise. Nothing revolutionary, just a bit of exercises in volume, light and tone. Images are from the September issue of Vogue. First one is a portrait from the editorial, and second Natalia Vodianova in Louis Vuitton campaign.
I wasn't going for artistic interpretation or expression, just wanted to work on my skills, but I do like how they look. What I love about watercolors is that they make everything look dreamy... But most of all I love how hard it is to control it. It is almost impossible, but that is why you work with them: it's like you and chance are working together. 
Almost like life, don't you think?
