Did you use a mirror? Or is this for left handed guitars? It's because a guitar never looks like that, not a regular right-handed guitar. When you play a guitar, you see the side of the neck, so you need to lean out a bit to see it. Or rotate the guitar so that you can see the fretboard. In this position the headstok is pointing to the left and the thickest strings are on the bottom, closer to you. For the thickest string to be on the top, you'd have to flip the guitar over like a left-handed person would do. But then the headstock would point to the right, and you're in the left-handed position with a right-handed guitar.
