Red, under the very best conditions is hard to capture...I agree with Anastasiatheo01 and MairanaEwa, but here is my two cent's worth...try a different colored flower while you are learning, and short of that go to the discussion board and search for this type of advice or start a thread...there are a lot of people who know a lot about these types of shots.. I applaud your boldness, sense of adventure, creativity and willingness to expose yourself to criticism and helpful advice :) :) :)PJ
It seems a bit overexposed.
