Seeing the wall helps a LOT. I think what this is lacking is perspective. If you establish where the floor is relative to the wall, it will help a lot to make things pop.
Are you familiar with one point perspective? Think of a point off the page. All your lines are going to lead into it. This will help you know where the ground is relative to the wall and you can add depth.

(Looks like s**t. Sorry. I don't have much to work with here.)
See how once you line stuff up, things seem to look like they are taking up space?
