Your title implies the flowers are the main subject of the photograph, but because of the composition I feel they are almost an accidental capture. I (personally) would like to see the flowers a little more closely, with more details showing. But saying that, I do like the way you have focused on the flowers and captured the background totally out of focus.
This is a really sweet shot, the Sparrow looks quite fluffed up, though I see this was taken in April, so it must have been a cold day! You've caught all its details brilliantly, but its a shame the bird didn't turn and 'smile' for the camera!
