Very nice work.  I see you modeled these items.  I find it tough to find scenes that can work with small creatures.  The textures resolutions are not good enough when you zoom in on small things.   Those books, that window and all those props are very nice.  

Do you know where I can get some decent props and scenes that allow me to zoom in like that?

Been there (some Rendo e-bots turn to be useful after all), seen it, love it. I can't think of anything that could be improved. The lighting is beautiful, and texturing - amazing. I don't consider this pic unfished, no way.

Yup ... I either model the props or find something that will work on a small scale.

I've got a book model that I got for free than you can have.  It came with one texture, and all I do is scan in other book textures and map them to it.

It's the same book model in both of my mice on books images.

I think I like it better this way.  However, it's late here and I'm almost brain dead.

The way UVmapping works, scaling down a model to match the mice shouldn't have any effect on the textures. But, the size you have some items, filling a large chunk of the scene, they need a texture of similar size to the final image. Or bigger. It's the size relative to the final immage that matters. You do have to be careful with procedural shaders. Something that looks right at human scale can seem coarse at mouse-scale. Again, it's a final image effect. Once the detail generated by the shader drops below the final pixel size, it starts to look the same. But this is like one of those "what is it" microscope pictures.

Are you talking about the window??  Because that's a reflection and specularity problem.  Not one of the image size.

Sweet!
