While this was drawn without looking at reference material, it takes inspiration from Warhammer 40k Space Marines. I haven't seen that head shape that I drew. (At least not on a dreadnought.)
This dreadnought grappler was drawn before my chaos dreadnought submission, which built off of this. While it looks faster, it isn't as intimidating as the classic dreadnought that I drew with the two chain guns.
