That wasn't blood, he just landed on a crate of jam as he leapt out of the window.
If they was blood, what the hell happened? Did he land on a kitten or burst some humongous blood blisters on his feet? Hopefully there'll be a perk which gives you better fitting boots or thicker socks.
Also, despite being able to see your character's limbs, it's hard to escape the feeling you're just controlling a camera when you get blood splattered on the lens. I think a far better effect would be for it to be a lot more blurry, clearing up as your character frantically blinked or wiped his eyes with his hand/sleeve.
