What you have here is a beautiful image, that needs a slight touch up. You should increase the contrast just a little, and maybe put the brightness up a small amount too. The drops of water are a fantastic texture, and although there is a little too much space at the top of the frame, its still a great photo..

I agrre with the above...a tad touch on the contrast will work wonders for this beautiful image, you have done briliant composing it, and the detail is very clear.......

The flowers are georgeous, but you definitely have to make them brighter. I wonder was it cloudy when you took the photo, then you should change the white balance override setting... Don't be afraid to experiment with your camera. As soon as you get to know it you will be able to capture what you really want.
