So, I've finished four of the Gold Skulltula pictures so far. Only about sixteen missions left in the original Adventure Mode. Then I get to do it all over again with the Master Quest pack.

Oddly enough, it's a little more restrictive. After getting to branch out and immediately play six missions, there's now only one place I can go, because everywhere else is either locked out by a wall, or by enemies that need to be revealed via a harp, which I don't have yet (items are specific to each Adventure Mode map, so the ones I got in the first map don't carry over to Master Quest).

Also, apparently confirmation of new characters for the other DLC. One coming with the Twilight Princess pack, and two coming with the Majora's Mask pack.
