I like what u did with the sky,very nice work,and because of that i don't understand the bridge and the people.Try to create some mystic image to fit with the sky...good luck

i made the background different and the bridge is meant to appear as if its going through those mountains...and into another world was a really hard image to work with as I didn't think the quality was very good for details

nice use of the faces good job i also loce the whole design as a whole good job

I like the people on the bridge, complements with the air . Personally I would skip the planets (how many tims you've seen them already?) but again, is just my opinion. About the people, the furthest girl is a bit too bright for my taste, is it possible to desaturate her more? Then she may fit better on the bridge. The kid in front could do with some more contrast/ darker, right now it looks a bit too pasted. Up to you. Good luck!

Great work!

nice job

the green child should be darker to match lighting around him/ her

if you look at the original source images.... you will find that they are ALL alot darker already.
