Ganesh, personally both of them are good but your "Dream of Wings" seems more complete. Let me explain. Back Home - gives me a feel of moving towards uncertainity with more blur from left to right while they return home. Whereas, "Dream of Wings" has all the elements with more certainity moving from bottom to top and naturally birds are more associated with freedom and sky and there is space above the tree which gives this feeling.

Just my 2 cents worth of thoughts on this.

Coming back again to this image.
After these many years I like to delete all my previous comments and just say "hats off".

Everything is perfectly perfect. My only wish now is to see a print of this image.
