Ok I see here that the build looks fine, but for being an actual builder you need to use real models you create.
Here is some suggestions:
1. Free Models as a builder shouldn’t be used, even if you don’t script well, try and get someone else to do it. Building something like a TV shouldn’t be an issue.
2. Materials! Try using some more materials for your builds, I just love the forcefield and brick materials! Try some new things!
3. The design looks simple, add more decor such as plants (Try using grass material for the plant itself) and a few other furniture pieces.
Here is something I created using some of those suggestions above just by using f3x building tools:
Looks like most of the models are free models?? The TV looks like its from the game Bloxburg. Try building on your own to gain better experience instead of using free models.
I am absolutely certain you have used free models lol. The TV when you were sitting on the couch was way too small in proportion to the build, also it looks like it has a stand on it lol, put more effort into trying to make free models look your own next time. You should use a scaling NPC. It was way too bright and way too simplistic. The door is far too wide and no hotel is red with no windows and just bright yellow text on the outside, all the tvs used have stands so i am certain they are freemodeled.
