Hi there,
I've worked the last 3 - 4 months on this warhammer 40k image. Together with my friend and colleague Martin Wyska I came up with the idea of making a great battle scene for W40k, but because we both are totally new to the whole universe regarding all the historical details I got many informations from my bro Tora2097, who is also a huge W40k fan. After a long time of gaining inspiration and knowledge we developed a few different concepts and ended up with the Imperial Fists vs the Chaos. The space marines are led by captain Lysander, whereas the Chaos guys seems to have the much bigger chief Dhar'leth - basically quite unfair but worth a try for Lysander

Every team has different support by tanks, dreadnoughts and all different stuff from the warhammer universe, nothing is invented - you basically could buy every piece of the image at games workshop. After the concept phase, the whole madness of modeling started:
Martin supported me with the following:
-The big Chaos Titan, all the guns, the Dreadnought and the Chaos cybots.
I modeled, textured and rigged all characters in the image, which was a ton of work, especially Dhar'leth. Afterwards I rendered the complete Image in dozens of layern out with VRay and did all the post work on it. The original size of the image is 12000 pixels wide the polycount i over 60 million. After two month of work placing all the characters I had to buy a new workstation, cause the old one laughed at me as I hit render at polycount of 10 million polys and shutted Max down...Back again with an i7 and 12gb ram it was a good workflow again

However, to maintain a stable scene performance I mostly worked with exported normal maps from Zbrush to Xnormal.
Allright, a complete making of will be available soon, I am currently working on that. So for now I hope you have fun discovering all the action going on in the image. C&C welcome.
Here is a much much higher resolution (4k)
And here are additional closeups in the original size:
