Thank you, alexanderH and GecT for your great comments.

I will resize that door, heheh.. It was the right proportion earlier, I guess I forgot to change that when I was scaling things.. Thanks!

And, I'm not modeling for games, because the game I'm making right now is in 2D (couldn't handle 3D games back then, when I chose a game engine) so I would probably be going more for photorealistic.

Not like super proffesional, but I suppose my goal would be to be able to model at least relatively photorealistically.
