Marine versus Ork

My friend asked me to do a poster to Warhammer thingy.. I have very bad memory so I dont remember the name of the thing but it had something to do with icebergs

So heres the whole picture I did. In the poster the characters are placed to opposite directions, ork to to top left, marine to lower right and in the middle is iceberg.

Ive never been into warhammer universe, it does seem like interesting thing but i just never got into it... I do like to draw orks thou But ye sorry for those WHfans if my characters dont look like they should

The picture is ment to be black and white lines only. I might add some more shading to this to make it look more darker but for now this here is what ive been doing apart of playing Dragon Age Im gonna do fanart of that forsure!
