I love the vivid colors here, especially how true the red color is here. Your depth of field is excellent. I also like how the white flower is obviously showcased, but your eye wanders to the others too. Very nice job!
I really like the subject and the composition. However the colors feel a bit wahed out and flat. The horizontal line in the background doesn't help. I wonder if you altered the angle of the photo or put the subject closer to the wall to avoid the line whether it would improve it.
