Hi RedFoxy, welcome to the gallery forum! I'm quite new here too.
First off, these are great images for just being a second scene! I'm already eager to see what you'll be making after 10 scenes/projects.
Nevertheless, there's always room for improvement, some additional info would always be handy. (Render engine, material settings of the ones you don't like),..
-The woodgrain on the window frame all run in one direction
-Windows are a bit simplistic looking
-Concrete texture doesn't tile perfectly and is a bit low-res/tiled too big
-Woodfloor doesn't tile perfectly
Maybe try to play a bit more with the camera (levelling it, focal field so the scene looks slightly bigger, etc)
Still, very neat work. Keep us updated!
Cheers,
Roo Evans
