Hello there! I’m XareezX, I’m a GFX maker and I recently made a GFX and here it is:
Now I know it does not look good… But bare with me I haven’t been making GFX for over a month so please don’t judge me. 
(fixed the lighting)
Software: Blender
Photo Editor: Photopea
( I said for improvement for later GFX)
The GFX looks lame, you should improve the lighting and more effect. The black rock looks very bad, it’s low poly and looks like only has a black texture.
You should add more detail like more people or gun or fire or smoke or plane or tank or blablalbalbalbalbalblblba.
Lighting could be improved on. Other than that it looks good.
I would recommend adding more soldiers, tanks, effects (e.g, Explosions, Gun fire flare, ect), Vibrance, and better textures on the rock.
Also lower the amount of blur as these objects seem rather close meaning they shouldn’t need to be blurred so harshly.
Needs more things and detail to surroundings
military in london? why? lighting doesn’t match all the supposed smoke and fog there should be, character’s accesories are like SHINY, posing is ok, but why is there a giant metorite in the middle of the street? it’s alright, but practically, the design doesn’t make sense
GFX will look dope if you pay more attention to lightning
This text will be blurred
Seems pretty decent. I think you should add some mist effect near the hill that the soldiers are walking down. Other than that great job 
You talking about the green thing in the left? If you are that’s not a meteorite that’s a bomb.
no, all this gray rocks on the ground
