Sci-fi Avian Alien Buildings

WIP Blender render, original concept.

Rear building comprises a central lobby area with rising elevator spire, the top tower is styled to look like a futuristic birds nest and although not shown in the picture, has channels running down from the top to the bottom of the tower and the same with the smaller tower below. With 3 smaller buildings anchoring the nest (like branches in a tree) and a forth building in front with more of an admin style design and function (comm antena on top in place of the support anchor for this building, with harder edges). The top dome is shaped like an egg.

Centre pyramid has vegetation growing along each supporting beam like a trestle, and the top social viewing area, which leads to a sci fi hangar area, with leaf / arrow head shaped landing pads and hangars.

Left pyramid has a cylindrical centre shape with conical shaped walls carved into the front and rear of the pyramid, the sides being more of an angular pyramid shape.

Right pyramid has a sphere centre shape carved into the front and rear of the pyramid and conical walls merging into the sphere, the sides being more of an angular pyramid shape.

Placeholder textures and environment, showing a central fountain and a social park area.

Concept idea, Avian like alien culture, their structures reflect the world around them and their heritage (hence iridescent textures, nest and branch like structure form, grand open spaces...), the pyrmid idea came from a basic design language idea of pointy sharp swooping down (like a bird) lines, perch points, strong structures and inverted nest idea.
