That's not a 'slight' reflection, that's a mirror image. Tone down the reflectivity of the floor tiles.
Texturing the walls didn't make anything any easier to see, but the contrasting helped.
Glad to see the lighting improved in the second shot.
Hit the other parts with some kind of textures. Get them out of the default 50% gray. I like to use a medium blue. It's just bright and dark enough to show off the details.
