Luke, this is a good and solid MOC without any doubt. I know that you're a brilliant builder, so I'm surprised. I'd have loved to see a bit more - background or other characters from the movie. Sorry, but my vote goes to your opponent.
You did a great job on Blain, but for a competition like this, I think you should have tried to do a little bit of scenery around him, e.g. a big tree trunk and some palm leaves and bushes. Taken a few photos with Blain in the scenery to capture the scene in the movie and then a few shots of him outside of the scenery to show your craftsmanship.
