That's cruel! Different sources were brought together quite smoothly and you paid some attentions to the detail such as changing the colors on the house. However, I have some suggestions for you:
1. If you want to focus on the two people and the house, they should be the main objects, so their shapes, colors, etc. should be noticeable compared with the environment. Consider that, the sky and the fire should be more desaturated and brighter in color, you can also blur them slightly to make the better depth (including the road and the hill).
2. Applying the motion blur is a nice touch but your choice of object is not right. The flight is so far away from the ground, so their movement is slow compared to other actions or movements on the ground and close to the camera. The camera has to capture the image within several seconds to see that effect, but in this case, the remaining parts of the image will be overbrighten and almost nothing will be seen. Just apply that filter to something close to the camera and move very fast compared with the others .
3. Let see the shadow of the house, it's sharp, so the shadow of the soldier should be the same .
Hope that my comment is helpful to you. Good luck!

I like this entry very much author...idea is maybe a bit cruel but that was our history, and we never should to forget all horrors that war brings...and now for the execution,i like almost everything...only one thing bothers me...sky is to blue compared with the ground...i know is to late now but for some other entry's u could create some color adjustment layer above all other...in this case maybe, dark brown color layer and maybe gray/blue soft light layer with low opacity...u always could try with some colors, never know how the things will turn up...Best of luck for u...

Sad....painful......but an interesting image..... your idea is good. Good luck.

Twisted! GL!
