At last, it's finished! I made some minor corrections, and I added a distant city beyond the mountains. This is the largest, most detailed and time consuming piece I've done until now, and I'm quite proud! In full size you will see only the 1/5th of the original size (which is 3600x3600).
All the models are created by me from scratch in 3ds max, except for the weapons, which are the free sci-fi firearms of Daz3D. The scene was renderded in 3ds max
and the background mountains & sky were created and rendered with Bryce. The final compositing and post process was done in Photoshop.
