Post-OGR ideas (What If? Metropolis)

In the OGR, the city I had envisioned was exactly like a cell and had buildings almost exactly like Haeckel's designs. After the feedback I realise that my development was quite limited and I wasn't taking in enough research in architecture and other artists.

To start to steer myself in the right direction I am going to research into the people that Phil suggested and start to break down my city and building ideas and see what works, what doesn't and what need more development and experimentation. Overall one of the things I realise is lacking in my thumbnails so far is a sense of structure.

Any and all feedback on this post would be helpful.
