They’re all pretty awesome but most of them have things bad that stick out (I’ll number the pictures and make good points too):
1. Posing is great. In-game blood effect stands out though and newspaper on the floor is in a strange position. I think it should be flipped over to make it look more realistic. Overused muzzleflash looks too thin and is not giving off enough light.
2. The cockpit ripping apart is awesome but the explosion looks strangely cut off at the bottom. Smoke isn’t so good and is too grey. Lighting is good.
3. Dust looks too much like smoke and is too consistent and opaque.
4. Muzzleflash looks really cool. Sky looks odd though because it is quite clear but there is not enough contrast. Also, tank cannons don’t recoil like that; it looks like the turret is flying off.
5. Nothing wrong here. Nice picture. Camera angle is cool. Muzzleflash and lighting are both good.
6. Good detail and posing inside the choppers, although it’s pretty obvious you duplicated them and everyone inside.
7. Great posing. Overused muzzleflash looks a little odd.
Overall, great posing and good work putting together such an impressive amount of pictures. Work on your editing though.
