Environment Design Rocks!

Hey Cyprinus, I really like the concept of your piece! Derelict ocean mecha = pretty sweet :)

I have a couple suggestions for places to get ref images that you could pull from for the robot design:

Since you're looking for a more Evangelion/anime type look:

Fighter jets

Stealth tanks

Stealth helicopters

Supercars
https://www.google.com/search?tbm=isch&q=supercar

If you have a general shape you want to use (human skeleton, right?) you can probably at least get started by just cobbling large details from these references on top of the base shape and you'll get some interesting looks. I'm guessing the Evangelion designs probably used a lot of fighter jet/supercar references bolted to a humanoid frame and "organicized" a bit by adding some bends to make them look a little more anatomical in places. They tend to have chest/head areas made from pieces directly cribbed from vehicles (wings, exhaust ports, missile pods, etc), with the limbs being a bit more normal organic forms with just armor plates going along the forms + some wing/fin/exhaust cowling details on the forearms, knees, and ankles.

The Pacific Rim ones are a little more varied and add in reference from industrial robots for the joints/underbody, I think, but the same concepts apply.

Hope that's helpful!
