Eon has a big dream: rebuild the whole solar system in 3D — the Moon, Earth, Mars, Jupiter. He tried something like it years ago and lost the file, so this time they'll do it properly, one object at a time.
The pro secret: use a real reference
His earlier space scenes were rough. The fix his dad teaches is the same one real artists use:
Don't guess what something looks like — look at a real picture of it.
For the Moon, the best reference exists: NASA's actual photographs. They show the Moon's real craters, shadows, and grey color — far more detail than you'd imagine on your own. With that photo on screen, Eon's 3D Moon can be made to match reality.
Why references matter
Working from a real image keeps a model accurate and believable. It's true for 3D, for drawing, for everything: the closer you look at the real thing, the better your version turns out.
Try it
Before drawing or modeling anything real — a planet, a pet, a car — find a photo of it first. Notice one detail you would have gotten wrong from memory. That's the power of a reference.
