Great work, man…however I agree with ecura. There is too much going in and everything seems important. The upper and lower third of the image are going great. For me the middle third is a bit too confusing. Perhaps you could let the observer breathe and appreciate the middle, by reducing details and reducing some of the contrast, like you had in post #40. I know it’s easier said than done…
I think that perhaps the most confusing elements are the big smoke trail to the left and the ship to the right. The smoke trail looks too much like a crescent moon. Try cutting the upper part, where it arches to the right.
The ship crashing into the clock (I think the perspective is a bit off on the tower) is a bit confusing, too, but it’s too important to change and it’s looking great. Perhaps you should remove that white arch above the ship, and if you could move the clocktower and the ship a bit down it would make more space above, leaving some “breathing space” for the viewer.
Great work, man, and I am sure it will look fantastic in the end.
