Not bad, not bad at all. It was nice to see all those units we haven't seen yet through spoilers, and it does help a lot to see the units in action.
A few suggestions though:
-Did you ask for permission to use the EB music? I'm not so sure about using it, especially if you already integrated it into the mod.
-For an extra bit of immersion, I'd suggest you to (somehow) keep in the battle sounds. Like the steel clashes, cries and whanot, helps quite a bit to have a better picture.
-And because of the same thing, In the battle shots I'd highly suggest you to show a bit more of the combat footage, in the sense of seeing more units in the screen (have the camera higher). The skins, animations are all great, however, the engine isn't that much (to today's standards), and not so much can be done about it. Take advantage of the good things of RTW, like the amount of units you can have in the screen at the time. Was it because otherwise it lagged to much?
Anyways, I enjoyed it alot, especially seeing it in HD. Great to know that this mod is so... alive, in a way
