X-Wing Blue S. / Forgotten Titans. With every new project I learn and discover new things. I'm still trying to find the perfect materials and techniques to represent different kind of landscapes... "Sand" is one of the hardest, which of course depends on the scale of your models; The smallest the model, the harder to recreate the scene.
Selecting the right materials will depend on if you are doing a permanent diorama (which in many cases would be the best way to go) or if it's just done for a production without "compromising" the scale model... Anyway, so many things to consider, but for sure there is no better way of mastering your craft than practicing and trying new things. X-Wing Blue / Forgotten Titans was built and painted at my studio.
