Notice the relationship between how you have positioned the flower within the frame and the direction of the flower within the frame. In #1, the head position of the flower is in the top right and its direction is upwards. A better composition would be to lower the position of the flower in the lower right so that it would have room to "breath". Whereas in #2, you have created such a balance. Although #2 is better composed IMO, it looks soft focused. With an empty backgroud as you have, I would stop down the lens to it's sweet spot, usually in the f/8 range, so that the entire flower was in sharp focus.
