Mall Bomb (newbie)

[StickyLabel]

Hello, I'm new to this website

And I'm not really sure what the idea is. I did this in photoshop using source pictures from google (Shopping Mall, Pole vault). Is this ok? It's not for any reason, and I didn't know about the mall bombings in Spain, so sorry about that. If I have got anything right, advice would be appreciated.

Another one, I still don't know if I'm doing anything right though.

In the first one, you are missing highlights and reflections of the fire.
In the second one Contrast and black level don’t match
And in the third one, the matte lines are too visible…

It seems to me that you are choosing complex subjects.
There are simpler subjects such as the one in the challenge and tutorial section of this site to start with.

I am no real artist myself so my opinion is from a normal persons view. ;)

I thought the first picture had no flaws, everything seems right to me. Very well done. I especially like the flying people. looks quite real with the blur effect.

On the scond picture the new mood of wooden house and surrounding grass is interesting (I like it) but the lighting on that mountain doesn't seem to completely work with the first part of the image. I'd also remove the pink/red tone in the sky and maybe add something interesting in the left part of the sky. Some cool clouds that go with the greenish/grey color-scheme would help the image.
Not too much clouds though, the lighting on the house suggests that there are not much clouds in the sky....

I generally like the 3rd image too but did notice this:
The center cloud is just huge. It looks like a big bad alien spaceship in disguise ;)
You should put more work into the lightning bolts and connect at least one with the ground.
The light on the front part with the soldier doesn't seem to be right compared to the complete rest of the picture. Make it darker.
The tower-like structure in the center of the picture has too much light on its right side.
Other then that good image too....
