this is very nice. The action seems very fitting for a stage in a game where you're overwhelmed by tons of monsters! It really makes you want to look around at the piece to catch all the details. Theres a lot going on, but not so much that it makes it visually confusing. Good job.
I can imagine this took some time!?! Looking sweet! If I may... I'd love to see the main 4 in the center tightened up a little more. Currently they are looking softer to me than the foreground dudes and it's losing some focus. I keep getting drawn to the boomer and the mauler since they have sharper details. After the center is tightened the foreground dudes might need a very slight softening since they really do appear to be the most in focus compared to the rest of the image. Other than that, I dig it! Great work.
