I think the background could be improved a little more. The flowers themselves are very well done, perfectly sharp and colorful, I just think there needs to be more to the composition. The background could be more smoother or entirely repetitive instead of having odd crossing blurred shapes. I think if you consider somehow finding a way to get closer to the flowers from a different angle and pushing the background farther it would achieve better uniformity on the entire image. That's just two cents for improvement. The flowers themselves are excellent!
