Orthographic view has no depth, so it doesn’t matter the distance you place the images. If I may though, Blender is not easy, so of course it’s actually pretty hard, but it shouldn’t matter, we don’t learn things because they are easy or hard, it’s because we want to and we like doing it. A lot of people get frustrated very early on and abandon the whole project before giving it a chance and getting pass the initial steep learning curve, so you have to face the challenges with a calm mind and know that it’ll get easier and easier. And of course you have a great community behind you who can help along the way. And you can rest easy knowing the guys that teach here are literally the best out there. We see so many comments and reviews of people tired of watching YouTube stuff only to be glad to have found a place with structure and real teachers. So I hope you enjoy Press Start, it’s more a Blender Tech Demo than a tutorial. If you want to start from the very beginning, you can watch the Blender Basics and The Fundamentals of Blender:
