I agree with quasion on the lensflares they are distracting (in my opinion!).
Also (in my opinion!) too random, dudes shoulder, the plastic bag (??) and the shovel, where there should be dirt all over because they just dug that hole so there couldn't be any light reflected(?).
And I agree with Nevasoba, the people and the house look too much out of proportion. When the dude will stand up, he will tower above the house. I don't know if this is what you were going for but too me it looks weird..
And when I look at the way the girl is 'holding' the shovel, I probably would have turned the shovel around and let it stick out of the pile of dirt.
I would also try to do something with the sky.
Don't mean all the above in the wrong way, they are just my opinions.
