drawing- class

Hey,
today  went to a drawing class especially for drawing with oil colours. The photo shows how it turned out, still it isn't finished yet. My back does still hurt because of 7 hours standing infront of a canvas... well... it's a quite common subject (flowers) but for getting started I think it's not the worst idea to start with a still life. hope I can define it a little more next time and finish in the end. :)
