Look at that Xbox 360!
Anyways all of your work looks really cool. There's only one thing that I looked that that didn't seem right, which was the land raider. Specifically the parts where it seems to be rusting (could just be me). While the detail itself is magnificent, the materials that the Imperium uses I'm not even sure are affected by rust anymore, let alone the absolute greatest materials that the space marines use. On a more specific note, space marines would never let any of their equipment rust, even on the battlefield, as they're far too meticulous about keeping every piece of equipment in the chapter in prime condition because they're so incredibly rare and venerable.
At the same time I'm a retardedly huge fluff-nut when it comes to the Imperium and more specifically space marines, so it entirely could just be me.
On another note, the models do look glorious and I have to give praise on the color of the models. You've managed the Imperial Fist's 'yellow' better than just about anybody I've seen, most of the time they always get it wrong.
Lastly, if I could ask, where did you manage to get those kite shields? I've actually been looking for one or two shields that aren't combat or storm shields.
Anyways the models look excellent, do keep it up!
