An Orbital Marine from my fictional universe; Eternity is not Immortal.
Orbital marines are trained for null-gravity combat and planetary assaults, their characteristic, round 'fishbowl' helmets stand them apart from the rest of the Sumnian army, although they frequently remove them when on-planet because of its restrictive field of vision.
Feel free to make a remix skin of this if you want with an alternative head or colour scheme, the marines have a variety of camouflague. Please credit me if you do though, and send me a link, i'd like to see what things you can come up with.
For further information on Eternity is not Immortal please PM me and i will get back to you asap.
EDIT; just noticed that there is a slight error round the outside of the head, i think it's fixed now
