The placement of the purple flowers on a diagonal was an excellent compositional choice.The bee is also just where I think it should be.My only suggestion is that next time you pick a background that does not compete with your subject.Looking for a good simple background is an important as the subject itself.Separate you subject from the background by selective focusing.This is easier to do whan there is a distance of a few feet between the subject and backgound.Your work shows good seeing. Just watch those backgrounds.The light is good, but the softer light of an overcast day is the most ideal for flower close ups.
