Different
This was a cool I can see the struggle of the characters here and the use of detail is wonderful. You have lots of elements going on but you don't lose yourself or the theme in this piece. I do I wish it had some more vibrant colors but you were going for something darker to fit the theme here of assault, which is a very dark theme. It doesn't need much improvment since you have a cool different style here anyways nice job on this and hope to see more soon.
~~THINGS TO IMPROVE ON~~
Just more colors please in this that a bit brighter, maybe some deep reds.
