This is a lovely shot, I am not sure what programme you are using but your programme will allow you to compresst the size of a picture without cropping it down to nothing.
Have you gotten a lot of comments that people want your photo larger? I like it this size. I can view it on my screen without having to scroll and it seems delicate this size. If you have it printed, print it small and frame it large. It will retain this relling. I could do without the border. If it a strong enough photo to stand alone.
