First Choice:
Aidan. As Lucky Forward described, I thought it was very clever in that it actually told a story. Plus, it's aesthetically pleasing as well.
Runner up:
Lucky Forward. It was a toss up. I was going to go for soemthing else, because the tungsten lamps gave it a sort of muddy quality (maybe slightly underexposed?) - I get the same issues myself. But the execution and effort is impeccable.
And when did you get a 7D?! Wait, maybe I already asked this....lol. I really don't pass through as often any more. Just spurts.
Honourables:
Big Jonsson: I liked the link and use of the theme. Not immediately obvious, so engages the viewer.
alterno69: a nice emotional shot. definite honourable. Maybe even a runner up in an alternate universe.

Maybe you should've put them a bit more off-centre and give them some 'looking space'.
pringles: Awesome photo.
thatbox: interesting composition.
BLueTsunami: Love the photo, but not entirely sure it fit the theme that well for me.
Other comments:
Many of the photos are obviously just shots of toys. Which is fine, but something I've learnt about these kinds of images is that it's going to be 'just a shot', even in a light box, it should still be something that is interesting to look at, be it by subject, tell a story, lighting or what have you. I find it pretty tough myself, so I know it's not easy. I guess that's why I loved Aidan's and Lucky Forward's so much.
Agent Ironside: Nice angle! But the lighting and background is not flattering. It's a bit dark. My brother has a bunch of Hot Toys, and they can be pretty fun to photograph! Here's my favourite image that I took of, I think the same Iron-man in a light box:

Lumix: cool idea, but I think the colour cast is not helping it. Again, the indoor lighting is difficult to fight against for correctly exposing. A tip I learn aaaaages ago, is that if something is supposed to be white, make sure it's white in your image (goes for snow too, i.e. Cruncehd's image). If it's light grey, you've under exposed. Obviously, it's not a hard and fast rule - depends on what you're going for, but this tip helped me a lot.
nitewulf: great image! It's not quite as sharp as I'd like this kind of shot to be, however.
Also, another comment for overall - do pay attention to background. If something is not adding to the overall image, try to not have it in the image. This doesn't mean you have to have uncluttered backgrounds, just consider whether something is supposed to look like it is in a particular place or not. Even things in the background that you can't help can be made to work with an image as opposed to against it.
