I think the changing distance but not sure
I did not notice that till you brought it up hmmm I went back and looked at original pic It may be the way i framed it but it is defiantly part of the original shot
This is what it takes for me to learn i would not have noticed that
Thanks for the comments
Don't know what software you use for PP, but most have a relatively simple process for "straightening". You lose a little of the image, but you have room to give some up. Unfortunately I noticed that the "world was running down hill" before I really saw the picture. Love the ship and it is a nice clean shot. Why not try a fix and re-post?
