No, I doubt the bottom of that image will run straight like that in the real world. The POV would have it on a slight slant. not to mention the fact that it is straight makes it look out of place. You need to place it on the wall more evenly spaced, if it is centered right there, there will be a larger gap closer to the POV, not farther. You will need to adjust the contrast and add some lighting effects to blend it in, it is too bright and flat right now. A frame would be nice, but that might be a bit much if you are new to this type of distortion.
Try to use 1 point perspective to find the main point, then draw out your lines and see what that returns. Although, 1 point isn't true to actual perspective, just a good visual trick that looks good enough.
