Study: Light and Shadows

I was trying to study light and shadow using one of the picture from Peurto Rico trip and some imagination. I may color it. Not sure...

Kitchen Sink

I did this quick still life study. I used painter for the first time and really like the pencil tool. Its almost like drawing on paper - really cool! I am trying to paint it but have not achieved results that would make me happy. If it turns out good enough, I will post the color version here.
