I would remove the two planes (I think they are planes to the left of the moon). Then I would use the spot remove tool and drag it on that jet stream line above the moon and remove that. One great way that I have used to see if I like how it looks printed, is I send it to my friend Randall Bruce at Randall's Fine Art & Framing, & have him print it for me. You could have him print this 16 x 10 and see if you like it then if not go back to the image & fix what you don't like. It is not that much for a small print, from him. Probably looking at less than $13 depending on what paper you have him print it on. Do you know what medium you will be having the prints done on?
