This is looking great, FRAWG! You deserve better critique than I can give, but whatever!
I made you a really messy edit on the first mockup (some of things apply to the the other mockup, others are less relevant). Here are the main points, as I see them:
-The floor has a really well-executed texture and is pretty distinctive, but my immediate thought is that I would stub my toe every five seconds if I were walking around in the room. Maybe try toning down the contrast between the highlight and shadow to decrease the perceived sticking-out of the boards? Some areas already do this really nicely, too, especially towards the left of the room. In case it's any help, here are a bunch of wood board references -- most are from Frogatto, plus a piece by Cyangmou:
-I used filters to play around with increasing the brightness and saturation and shifting the hue more towards red. This could be a stylistic choice, but I think your colors could do with a little more pop.
-The planes of the tables/shelves could use more contrast to add more form; they look a tiny bit flat right now.
I wish I could be more thorough, but that's all I've got for the moment. I hope this helps, and good luck with this whole project!
