I am looking for some feedback on this build I made in around 20-30 minutes.
If you want:
A low-poly building style
You should make it all the materials plastic, the models already fit the low-poly theme because they are simplistic.
A detailed and realistic building style
You should add more detail to it. Don’t use sand as the material for the walls, try images. Use the Future lighting, because it’s more realistic and detailed. Will drastically impact the look of your game, and should help it look more realistic.
Conclusion
Your build looks pretty decent, especially since it was only made in 20-30 minutes. If you want a low-poly style, make it more simplistic, if you want a realistic style, make it more detailed.
It’s lacking a lot of detail, seems extremely large for a bedroom, and the bed looks large for Roblox’s scale. Overall it seems to lack a lot of thought and the design choices could be better, but the quality is good.
That’s good, but I think the interior is too little maybe more can be added & the room is too wide for me.
Great Work 
Imagine if that were to be your room, would you want it to be that empty?
What I’m trying to say is that the room looks abit to empty, mabye add some poster decorations or some desk decorations.
But other than that, good job!
