The angle of the shadow is confusing, and the shadows are blurry, so it's impossible to tell if there is ambient light, or a strong light source, and what the position of it might be.

So I guess the first thing to do is to figure out the kind of lighting setup for this tile. I would suggest ambient lighting, because it would make all your tiles look consistent. In a setting lit this way you get very subtle shadows where objects are close to each other, so in places like corners of walls, or where wall meets the floor. The shadows are blurry and subtle. Here's an example: link

As you can see, with shadows like that you'll have to set walls apart from floors using texture, color and value. The look you'll get will not be as three-dimensional as if you used less light, but you will get way more consistency across all your tiles.

Also it is good practice to adjust your levels to avoid clipping when you're preparing your files for printing, so you don't get blacks that are too dark.
yeah, adjusting your levels should be the best solution. no point fighting in the dark.
