Hey Alexey, if you’re starting from zero it could take at least a year or more to learn how to create scenes like that. Perhaps a little less if you have all the time in a day, but realistically it’s not going to be a fast process.
That said, it’s definitely doable if you apply yourself! There are plenty of easier things to make that can keep you excited and encouraged along the way. If you go through our Intro to Blender Learning Flow, you’ll get a good idea of what it takes.
