Here's some early concepts I made when I started working on the idea. I knew I wanted to make some sort of religious symbolism in it.
I wanted to go with more priest/cultist look so I started designing these.
I liked the idea of corruption that is eating away the holy man, so I made more metal eating away the flesh look.
After few tests I wanted to keep the wing on him instead of making some other symbol next to the sun.
Also having sun on both sides felt like the design started to look too symmetrical and since the robotics are eating away the left side, I wanted it to have it's own design there.
And so this is the final sketch I did before starting the sculpting process.
I will post WIPs as soon as I get the rough sculpt base done.
Hope you will find the making progress interesting to look at!
