Beautiful weather

It's such beautiful weather outside, but i have to study for the university. Sometimes though I take a break, go for a walk, and do some sketches. Yesterday evening, the sky was so beautiful at the lake: the main difficulty was, that the light and the clouds moved so fast. Today, something different: blue, cloudless sky, so i sat in the shadow and sketched this nice little villa in front of this ugly big monstrum...

it even had a rainbow - i couldn't quite grasp it....
