Of course, the sensible thing would be to use an existing game engine, but after a certain point, there is some curiosity if learning and fighting yet another game engine is really quicker that just writing something from scratch.
Just a personal work trying to explore new techniques. Photoshop, Modo, Keyshot and Marvelous Designer :) hope you like it! I am always interested to be involved in new projects and I am available to work in case you need some cool concept art for your projects :) Cheers! R.
