grate texture blends too well with 2X4
The lighting is a bit bright.
The colors look all washed out.
Could you lower the intensity?
Looks great.
Tip: My monitor is going south, but you might want to consider changing the 2x4s to metal.
A lot of glare is reducing the potential good-ness this has.
take a look at your refract maps in the glass, that will be a good indicator of how bright a lot of your things are.
