Good composition, I really have a hard job by finding anything to be criticized. Probably some more depth could have been applied with placing the soldiers a bit further from each other (the one on the left side could have been put deeper into the available space) - that would have strengthened the three dimensional viewer experience. Great dramatic impact achieved by the main character firing outside of the frame. The reduced color palette supports the story a lot, putting more emphasis on the shapes and composition. Also loving the shape of the heavy body armor and the west - and of course the details of the helmets, which makes the wearer look "non-human" and supports their hostile act this way. Good job, keep posting quality artwork!
I have to start off saying that i really enjoy your work. Your very talented and I always look forward to seeing what you come out with next.
Now for this image. Over all i like it but there are a couple of points that i feel detract from it. For starters the characters in the front right firing the gun, there seems to be a slight proportion flaw....though i'm not quite sure if its the size of the gun or how bulky torso(i understand there is gear and armor there but still) and upper arms are compared with his hands and head.
The only other suggestion i have would be to create some sort of "particle effect" from the rear left characters hand to the Pyro Attack shes using. I don't mean anything obvious or too blunt but maybe just some implied lines or a "laser beam through fog effect" as this would help define what she is doing a little better.
-Vision: 3 because its a wip and not completed yet, i'm sure the finished image will be a 5 start. -Originality: 4 because i really like how creative you are with your armor designs and your "super powers" -Technique: 4.5 you have amazing skills and your putting them to great use here, only minor "flaws" if you can even call them that. -Impact: 3.5 once again because its an unfinished image, i can't wait to see the finished work.
