I stumbled upon that tweet. Those poses are really intresting. And this instantly gives an idea about more special modes for Miria in The Guardian Legend. She could have more versatile backpack.
Fore example that bow pose looks like for some powerful strike. That would work only in walking adventure mode. The other intresting pose is for softer and maneuver flying. She could fly to any XYZ direction with this. And very fast change the direction. And the third pose, I don’t know. Could be some other sort of fire mode or cutting the walls.
I think there could be a special section in the Gallery for stuff like that. And check that tweet it has more images.
