I was at FFWD.PRO conference for the past 2 days. I took 3 different sketchbooks and drawing tools, but barely used any of it since I had little to no down time.

Yesterday when I waited for my pizza to arrive I sketched a bottle, and then colored it partly in the bus and later at home just so I could justify bringing the watercolor kit with me.

And this was my attempt of sketching my boyfriend which isn't really good at all but eh..
