I can see where you were going with this author.. try to add some shadows under the speakers.. darken the edges of the the baby picture and it will give the illusion of depth (some burn will help with the overall image ... (but remember.. it is YOUR vision.. and what I suggest is IMHO) good luck (and sweet sweet baby... now wait for the drooling LOL)

nice work author...create some shadows under the megaphone...best of luck

I made some little changes, added some shadow and burn as suggested.
Thank you erathion and Drivenslush for your comment.

You should have made a window out of the doors frame, so that they won't look out of scale and half burried.
Rule of composition: repeating an element lowers it's value (2 yellow houses).
But it's a try, keep improving.
