I like the music, and I hope at some point we get full sized versions of the art.
That bridge at the top of the tree makes me happy, because it's more evidence that they haven't used dolls as a replacement for on-foot exploration. It's much more fun and rewarding for me to climb up twisted root/vine/branch structures than just wait for a few seconds holding the fly button in a mech. I'll be spending a lot of time on foot. The small details at human level will help me better appreciate the larger overall scale at mech level.
