After Effects / Test Exlopsion

I have been experimenting with After Effects for the last few months, today i have some good progress. I have been compositing some explosions and smoke onto live footage. For this test I used some stock footage from a dvd, for my final project i will be creating my own exploosions/smoke effects in Maya.

So i basically used some of the Film footage of my solider been blow up after a grenade is thrown his way. The only problem i had with this scene was that my actor dosent get blown to peaces one the explosion goes off. Im not to bothered about that the moment, I was more focused on accurately timing and colour correcting my effects to look as real as possible. I have uploaded some screen shots bellow, im pretty pleased with the results, although I am going to have to work a way around my actor disappearing. I have considered reshooting the scene, and possibly filming the actor over a green screen so i can animate him blowing to peaces.

So heres the screen shots, I am going to try upload the actually video after rendering it to a lower resolution.
