The image is beautiful. However as was rejected for, it is a bit noisy. It is quite unlikely that you will take a photograph that will eliminate all noise. For that reason it is allowed that you use a noise reduction tool of a photo editor such as Photoshop or any other that you have access to to remove noise, or to make any other necessary corrections. To identify the level of noise in your photo, zoom the image to between 100 and 200% and inspect it for grans, or artificial color spots (color noise/artifacts). In the case of the image you upload to this forum the blurred background has many small grain/dots when zoomed up. Also you need to inspect the edges of your image for sharpness. I believe the depth of field of this image is too shallow hence producing too much soft edges of your main subject. You can inspect this at 100% zoom at what size the image should still be sharp at its edges.
