Hi everyone, I’m pretty new to Blender and have been trying to learn how to pull of some low-poly designs.
I would greatly appreciate any tips or critique to improve the design.
The models looks super fine, I’d just tweak the colors a lil bit. Adding a little color variation to the tanks would bring out some details, and I’d add some small variations to the dirt ground, like sedimentation stripes.
But all in all looks goods, really consistent!
Maybe add a smaller gun on top 
More grass, more trees, maybe add in bushes and flowers. Also more colour variations.
