its all good except where it changes to blue from red in a perfectly straight line. in real logos like this (for all sports) the white image goes from top to bottom, and is the divider between colors. you could use one of the blood splatters to be the divider, and it would looks 10 times better.
I can definitely see what you were going for here, but I think that using the picture of Marcus killing a Locust soldier with a chainsaw is too complicated to use for a logo. The problem is that in the style of the MLG logo, the render must be completely white, which makes it hard to identify what is going on in this particular image. I would try a simpler render on the same background, and see how it turns out. Aside from it being a bit hard to tell what is going on in the render, you did a great job replicating the style of the MLG logo. Good work.
I also think that they should be chainsaw dueling. One team shouldn't be chainsawing the other team in my opinion. It makes it look like red team/ locust, is the loser.
I think you should just make it one guy holding a chainsaw in an upwards position so it doesnt leave a straight red/blue line. good job though. it looks pretty good.
To guys in a chainsaw battle or 'clash' would definitely work here, and they could be the cut off from red to blue since they clash with them held up, good attempt but it can be improved by this, keep the colours as well, or it wouldn't be MLG and those shades of the colours look great!
