@Cognigni
nooo, sorry. but you have structure separated by Internal and Armor.
Also you have separated limbs, so it is very easy to see inside just hidden parts.

@RamdomGuy4
nooo, "samui" is an expression like "It's cold/I've cold".

@An0nym, not my creations, most of them are done by the reference author in brackets.
I also do a reference to the their work in comments and add a link to the source, if exist.
In this case there is not source, cos it is old, but you can visit the Flickr to see the impressive work.

Te only one done by my self at the moment is this:

Not a new design, it is based on an old Anime, with a propriety Sunrise license.

And a render to show, jokingly, the horrifying face of the monster mode.

Added a 4th finger cos in monster it rotates arms and the thumb go down strangely.

First test to share a Pinterest image, not sure... Does it will work?, it never works at 1st time

Hope this render keeps alive, I spent long time in Blender to do sand dunes

Another alternative build, cos...
