See that red thing in the middle of the title panel?
That's meant to be a circle, 
you have turned it into an ellipse, .
In of itself this isn't a problem but the distortion is carried over to all the elements in that section of the composition.
Like your earlier attempts you have squished our heroes.
The central photo is not to the same resolution standard as the rest of the image components on the cover.
There is a visible grain where you have added the image over the original clean background.
Just a few pointers but as I said before if you are happy that's fine and dandy.
