How the guard lost his legs, we may never know.
This was inspired (if not almost directly copied) by a Splinter Cell themed room in The Joint by jujucece. This is not really meant for The Joint, but it's my first pixel art submission and I'm still trying to figure out how to work my program, so I just used an existing template. | 
The blood looks more like pink pants.
Try giving it a darkish-reddish color.
Maybe make it look more like a puddle, too.
Be sure to add a little shine to it.
(The dead gaurd also needs alot of heavy work. He doesn't look like a guard, and the way you made his legs cut off looks really weird.)
The bandanna thing on solid-snake is also strange. I thought there was gravity in MGS.
