Everything except the uniforms, and rifles where made by me (including the tank)
some one show me some art
The render seem realistic , but the rest does not look good because some characters are not well positioned in the ground . The desert hills are too dark compared to the rest of the Thumb, and above all, I endorse what he said Duducateu. Good Luck For The Contest Man.
The hills in the back could have been progressively getting darker right now it looks like it was simply put in using photoshop. Like what duducateu said lots of minor things but still very nice.
I'd say really good. But maybe some boning to the character actually holding the guns. Maybe one kneeling down with the gun as well, sitting on the the tank. There's lots of things could've been better. But this is still pretty good.
