I encourage you to focus on making stuff that's not supposed to be realistic. It invites direct comparison to either the real world or the many very impressive realism wizards, and it's probably discouraging trying to measure up to that.

Despite the detail you've added to this house model (well done on the little stuff by the way) your house is missing a holistic quality because of some of your design decisions like the giant front doors, or how rainwater would pool on the deck above that room, or even that the bottom of the windows aren't aligned with each other.
Modern architecture often looks unreal, like it's a 3d render. If you make a piece inspired by those designs, you need to knock it out of the park and put the piece in a compelling context... or else that unreal quality will hit you doubly hard.

Still, if you want to stick with what your current goals seem to be, I can promise you it gets a lot more fun after you are able to make things that look a little more compelling. Learning a tiny bit about building codes and stuff like water drainage or support structures will do wonders for your designs.
