War Machine Cyborg Warrior 3D Model

This is my first study for creating a warrior character. This character should present a concept of a medieval soldier with a mixture of elements of the Steampunk style.
I did several studies and drawings of armor and weapons for this warrior, he has a mechanical arm with a gun attached to his hand.
I took the arm of the character Guts, from Manga Berserke as a reference.

Final rendering.

Sketches of legs and arms. The legs for example, I took reference to Robocop's leg.

First sketches of weapons.

Cannon and harpoon weapon options were studied

I had an idea to make electric weapons, whose energy generator is on the character's back. The mechanical arm is also a cannon with a shock gun attached to the arm.
