Great artwork but historically inaccurate. C130s did not exist during WWII. The paratroopers jumped out of a C47 - a completely different plane. To put this in perspective, it would be almost like showing a WWII soldier carrying an M16.
Yep, AlbertWesker is right, the tank shadow is missing, and the soldier is definitly too huge, because if you take the 2 tiremarks of the path, it's like your soldier is as big as a car (and obviously, he's also twice the tank's size). You could have reduce the blue outline of your paratrooper too, there is a feature for that in PS.
Anyway, I like the colors you used and the ambient.
