Oh, that sounds easy... But then there is making the terrain,

But... I have already given away a low-poly terrain:

So all you need is a nice rock texture and a creative mind [:)]

Here is a new tunnel:



When I was little, I practically grew up on a film set. I quickly picked up on the rules of the trade, and an old cameraman taught me how to make myself invisible. Never once was I scolded for being in the wrong place at the wrong time.
In my life as a child, there were two realities:
One reality was my observation of the world that surrounded me – and the other reality was the world created for the camera – an illusion, a universe with transparent rooms, made for the sole purpose of producing an image.

So when I create a tunnel, my sole purpose is to make an illustration of a tunnel. I only make it for the camera. What's outside the camera frame, if anything at all, is totally unimportant. I move walls, doors and windows, and I create backdrops and false facades, just to get the shot I want – just like they did in the fantasy factory I loved to be in when I was little.

You probably won't find any use for it [:)]



... and here is a creative mind:
