This looks like nice Tile Floor. I see that you use Blender. I assume you use it because it is free. Daz Studio is free and it is possible to get the pro version for free. If you didn't try it recently then it has gone through a lot of great changes. For a person that creates models it is good, but for others, they are doomed to buy models. I use Hexagon 2.5 and I was doing the rigging through Poser 7, but more recently it is starting to crash. That means I would need to do the rigging through Daz Studio, and it will do that, but it is not that easy. Some features helps like fit bones to model, and it self adjust. The main reason why I use it is because the lighting. It has all kinds of lighting, and they developed a good natural lighting with their sun light that can reflect in a mirror, and spread ambient lighting to make things look very real. I thing it would help your models to use it. It is just a suggestion, because I have Blender on my computer and never really used it enough to understand everything, and it has changed a lot too. I create lighting for inside rendering, and I noticed the emissive lighting from inside an object will look like it does everything, but it will not reflect light through a mirror. There is a subsurface lighting that you can make maps for to show blood vein under the skin. I don't really know much about it, but I have used it. The map is marked with SSS at the end of the name. I just thought it could help you get more realistic renders so everything looks better. I can't lie, but it might be easier for me to understand it while you understand Blender better than me. I think just clicking the render to start it will make a nice render, and the render quality is the third menu item on the render setting tab. It normally set to 1, and you can set that very high. I set it to 600, and it could finish when it looks good while setting time and other things to the max it is really the quality that keeps it going to get a better render. I have a question about Blender now, I think I have the latest version so that is not a problem. Does Blender use maps for everything like a gloss map to make one surface shiny, and other areas dull, like your tiles, could the design be glossy and reflect light like it has glass there and the terracotta dull look for the background. I have not tried to render anything I made while they are obj files, because that seems like a universal type that works in almost everything. I put things in the Blender world and didn't do much. I have to learn how to rotate and move around the scene, because it has been a long time. Now I know how to move around again, I am still working to get back into it. I don't know enough to get a good render so I still question if it is worth it, since Daz Studio seems to be better to me. While I will be ready to do all I can it I know it can do things like grow hair strands and use wind to blow the hair, and I can use that to grow grass and render the wind blowing the grass. Then cloth drape so as people move the dress moves in the wind and gravity makes then fall if it is not strapped in place, because it don't pass through the surfaces you list. This is what I liked about Poser, and if Blender can do it, then I will learn more about blender. Daz Studio can do it, but it needs 3D party stuff that we pay for. Then I noticed some things that is made to drape explodes, and crashes the program.
