I decided to share my newest picture with you for any critiques and comments.
Total time needed was about 2 days, time for modeling in 3ds max, shading and rendering with V-Ray renderer and photo matching the rendered gateway into the source image, included.

On this picture, a new gateway is shown, which shortens the way between the several departure and arrival gates on an airport. It should leave it possible for the restaurant's guests to watch the departing and arriving planes, even if the gateway is built. That's why the the "tube" is contructed mainly out of glass and stal.

So, what do you all think of it, especially if you kepp an eye on the fitted 3d-model of the gateway?
