Working from my form silhouettes I collaged different shapes together to create pillars, which are the main forms of my exposed coral city. I am drawing a lot of inspiration for this from this image.
After creating quite uniform silhouettes as a base, I then started combining different forms together, creating more free flowing shapes. I have highlighted 37 and 42 here because I particularly like these structures.
I have experimented some more with combining different forms to create irregular, more natural shapes, and have also begun to draw basic details over the top, as well as taking inspiration for an apartment block-like complex from a coral.
