Well, it seems your perspective is off from looking "real". It seems you're going for the classic room with doors on the sides, that vanish towards a single "vanishing point". Thing is, the room doesn't vanish correctly. For example, here's a simple grid to show how perpendicular walls would vanish in an ideal single-vanishing point scenario:
As you see, to match this, your mockup would have to look more like this:
Just a quick 2 minute sketch/guesstimation. Angles/proportions obviously aren't correct, but it shows what's more correct to what you want, with a better sense of perspective. You'll notice that the doors look different sizes yet have similar angles, just smaller lines.
(EDIT: Also, are you aware that if you need to say something more but already made a post, you can modify your last one instead of making a new one? 'Tis the button in the top right of the post.)
EDIT2: I guess I didn't answer your original question. I'm not sure what it's called, if it's called anything, but one thing for sure is that it doesn't feel of a 3-dimensional space, and hence doesn't provide true "perspective". Unless that was actually what you were going for?
