Well thats how it is, The guard don't fight without the Astartes and the Astartes don't fight without the Guard. Without either of them, the Imperial of Man would be nothing. I love that Astartes in the middle.
great work, really amazing. i am particularly impressed with the clear and accurate perspective and objective point of view. i find that a lot of 40k imagery is layed out too abstractly and unclearly to figure out what is even going on. great work again, keep it up.
