First one. The red is too random on the second, it doesn't fit with the red on the focal.
One this I suggest is either smudging up or cropping out the very left-hand side. I'm not sure what those horizontal lines are there for, but I don't think they help at all, and it would look better to just be rid of them. You could do more with the right hand side OR reduce the size of your focal. It should take up about 1/3 of the signature, generically. Clipping masks would also be nice, and if you burn the left side of your focal, it will add better lighting dynamics. Lastly, the flow is a little weird, it's going from bottom-right to top-left, but your focal's flow is going strongly left-to-right. Last thing; the explosion seems like it's in the wrong place, if you look carefully, it's too far down, and if you're REALLY picky, it doesn't look like it's coming from the gun.
It's good, though, colors are nice in the first.
