I started the lighting all over again I think it's looking better now! I used many spot lights and a couple of point lights for this.I don't really like how the mia material of the glass on the right looks, but I'll fix this after I finish all the painting (at least the ones being refracted/ reflected) to see how it will look in the end. One more thing that I'll fix for sure is the little gap under the door and the floor, you can see the light leaking through it.
And then I'll probably have to adjust intensities after I'm finished with texturing . I myself am really curious to see how this is going to end up looking like lol
