This concept is about to preapre you for a Russian space cruiser which will be my last battleship concept for now. (add two more fighters)
Here is on of the thousands of Russian Imperial Space Sailors. They are equipped with oxygen bottles and a heating device combined with them. The sailor wears a rubber spacesuit and four layers of clothes, the last being the uniform. The sailor also weras heavy, iron magnetic boots, which stick him to the deck and prevent from flying away into the void. Note that this marine is an experienced one, and was awarded several medals. He's also been promoted to a lower officer rank. Officer space uniforms differ from the private uniforms only in rank markings.
The band on sailor's left arm has an inscription in Cyrillic saying "Kosmicheskiy Flot", which means "Space Navy"
This took about 2 hrs, used a HB mechanical pencil, Stabilo pen for inking and Lyra coloured pencils.
