Azathoth, the final creature in my Lovecraft series. The design was inspired by deep sea slugs. I ended up designing the "circle" at the center that is Azathoth at the same time as a globe and as a tunnel, depending on how you want to see it.
Azathoth
Detail
Tentacle detail. The tentacles are inspired by real world sea slugs
Cosmic dust detail.
Eye detail
Tentacle detail. The light of the cosmic matter illuminates the translucent tentacles.
Eye detail. Each eye represents a fragment of the 4 dimensional world. The yellow eye symbolically represents the 5th dimension, one that is above our natural law of physics
Azathoths center. The round shape is both, a tunnel and a globe at the same time, as we can see tentacles emerging out of the black tunnel which immediately start encircling around the tunnel, thus creating the impression of a 3 dimensional globe
