I really like this element of your style as well. The raw, energetic pen strokes are also very appealing. My suggestion would be to sharpen the details around the important visual elements in the narrative, guiding the reader's eye across the page from one point of interest to another, while maintaining the softer blending in the background.
Although your style is wonderful from an artistic standpoint, it seems to obscure the action at times.
For example, initially, on the first page, I wasn't sure if the character firing the weapon was the narrator, your protagonist. The drawing is positively "zinging" with great gesture and energy, but his features are all but obscured. I don't get a good look at him until the bottom-left of the panel. (Remember, this is my introduction to your character.)
Perhaps, anytime he's doing something plot-worthy you could sharpen and heighten the contrast around those areas. Also, when there are two or more characters on scene, try to bring out distinctive features of each, so dummies like me can tell them apart.
All in all, it's a cool comic. Love the gritty storyline and your character [creature] design.
Cheers.
