It looks really well made for 30 minutes. I feel like it’s a little bland though. If you’re thinking of working on it longer then I’d say add an interior and a couple more details on the outside. Other then that, 9/10
It looks pretty good.
I recommend you to turn up the rendering quality when taking pictures of the build you want feedback.
Also try to make the windows a bit more visible
I personally think this is amazing! 30 minutes isn’t so bad considering the detail in this is up to perfection.
It would take me a few hours to make this. Good Job 
Looks Amazing Really Cool Design. If I were to use it in an RP game I would Probalbay Make it a Pizza Shop or Some Food Store.
If you want, you can play around with the colors, and possibly add some textures (if you were using this building for something). But overall looks good!
