The thing about 3D renderings is sometimes you have to exaggerate things and improvise, if looks good it is good. As an example a lot of people put three lights in a lamp like your bed side lamps, two spots, one pointing up and one down and then a point light right in the middle. It’s because lights in 3D packages don’t really represent real world light exactly.
Have you worked with the post processing volume too? You can adjust min/max brightness in there, it’s basically an exposure control as far as I can tell.
Thanks RI3DVIZ. I’ll look into textures for the blanket. Right now I just have a fabric material made up. I have the min/max set to 1 right now.
I think when it’s set to 1 in min/max it is disabled as I remember. Anyhow, I usually start by having my sky blasting light into the room to get a basic brightness, then add a sun for highlights and contrast, then I adjust the min/max post processing and other post processing parameters to get a decent light level. From there it’s a matter of putting lights in where they actually are in the scene.
When I set the skylight and sun to default. It was dim even around the window and by the time it hit the wall, it was getting pretty dark. So I adjusted them. But when it looked good in the room, the window was too bright. So I lit the lamps, then did skylight and did that til it filled in things nicely, then added the sun for shadows.
Here I am with new bed textures and lighting.
Looking good man, great job!
It’s looking much better! A few more suggestions. That near corner of the bed spread doesn’t look good, there’s too much fabric, the far corner looks good. The displacement on the carpet looks a bit heavy, the drapes could use a fabric texture (bump map) and I would square up the camera (you can always increase the field of view a bit to get more in the image), nothing says CG/bad photography like a Dutch angle. 
Also, put an image out the window mapped to a plane - try it as an emissive image.
I do have the outdoor done, but can’t be seen from this angle. I do agree with the carpet. I’ll look for something with the curtains, but not sure I know what. As for the bed, I’m TOTALLY done modeling that. Sucked to unwrap and looks like my bed at home when I made it up once. So I just copied that. Thick down comforter.
I totally understand, uv lightmaps suck! Here for future reference: /
For your background image make sure the horizon line is right, I do this in photoshop usually but too lazy this morning to turn on that computer, so forgive the crude example.
I wanted it to look like you’re on the 60th story. So at the window its a good view.
The horizon line doesn’t change you need a photo taken from up high, like an airplane to get that feel.
I’ll get a screenshot up. Get my pm?
Yeah, I got it thanks! I’ll respond with email.
Done done and done. Here is the final video. Thanks everyone for your help!
