Invisible cities - rest of the thumbnails for the Spider-Web city

The rest of my thumbnails, all of them are exploring the city I chose - Spider-web city.

Basically the more I sketched the more ideas I developed which was really interesting. Even the ones that do not look like anything in particular led me to some concept ideas.

I think the keywords after finishing the concepts are: crystals, snow, bones (husks), chains, northern lights and spider webs.
