I'm speculating because this kind of photography rarely grabs me, but... it seems like the cool X in the sky is most or all of what this image has going for it. The rest of the frame is just kinda "meh". Also, I think if you crop it, you'll be left with an image that has no depth, so it will likely be even less interesting. :-(
The images like these that I've seen that REALLY grab me are the ones where nearly everywhere I look in the frame there is something ELSE amazing to see. That recent string of images posted by Gavjenks and Charlie were amazing examples of this.
