Thanks for submitting your work to us for review. Excellent subject, I really love to take and view flower images, specially after winter has just ended. Spring is a lovely time of the year. Excellent choice of focus on the flower and I like how you have the branch behind the flower in focus as well. Excellent choice of f 2.8 blends the background into a lovely backdrop that is non distracting to the viewer.
If I were to take this image I would chose to place the flower more towards the lower left hand corner. But this is just a personal preference and in no way suggests that you would need to do this. Keep up the excellent work and I will look forward to seeing more if your lovely photos in the future.
