I think there's a bit too much sky, the top 1/4 is kind of dead space and cropping would bring my eye down to the subject. Just my opinion though. Cool shot.
I tend to agree. Most of these shots have not been cropped, and frankly, until printed, it's usually too hard for me to tell. I am very grateful though for the input.
This is a vibrant image. I agree with the comment about a horizontal crop. Just doing so by scrolling my screen makes a static image into a dynamic one. Good work, indeed.
