jarhead marine

hi made a marine .. I have no idea of all the diffrent designs in it.
I know six .
most people will go. that is a 40k spacemarine.
but the other 5 insperation sources they cant guess..
going to use it in a space marine homebrew chapter(still no name).
been cading for 3 weeks now.. hopefully I will improve..
you need to rotate the parts for printing. I am new to this..
if anybody screams copywrite/trademark tell me what to change
