Interesting story. Here are some suggestions. I'm not a writer so take it with a grain of salt :). I did notice a lot of punctuation was missing throughout the chapter. Keep up the good work.

Willow stared up at the endlessly ascending buildings -> Willow stared up at the buildings that appeared to ascend to the heavens.

Willow was sitting there drinking it all in -> Willow was sitting there soaking it all in. OR sitting there taking it all in.

Willow walked over and sat on a coach that was closer to the door. -> Willow walked over and sat on a couch? that was closer to the door. /// Unless coach is a type of furniture in this world.
