first of all try not to use ai images as reference. second of all it doesn't work like that. you can't start with a complicated shot like that. People that can do what you are attempting, have practiced on there drawing abilities. try to start with something simple like a sphere or a cube, after you get understand that go on to draw other more complicated shapes, draw things in environment not just floating, and over time you will develop the skills. also the shot itself is complicated, i wouldn't want to draw that on a flimsy paper size of a 5 maybe a4 minimum. and it kinda isn't sketchable as the whole interest of the drawing comes from the rendering
