Honestly, at first I thought the second sprite was a backflip, due to her pose.
But the jumping one is nice.
And I'm all in for idle sprite.
I'm just wondering where you'll fit them in, considering that 2 character gfx can't be loaded at the same time(as far as I know, NES can use 4 chuncks of gfx(for the lack of a better name) for sprites and 4 for background), unless you sacrifice space in one of 2 chunks of gfx that are used for enemies or the one used for HUD.
You did say something about only using ropes, but then later you said that you might actualy use both stairs and ropes, so you'll probably have to reuse some sprites for different animations.
