Last week, while talking to Nick, he made me visualise and avoid a future dificulty I could have.
Before I was modeling the building using a primitive cube, and Nick said it would be dificult to open the UV later since I would have so many details in only one shape.
Now, I was advised in separate each wall into one individual plane, and build each part of the roof individualised too.
I was also thinking of making the side wall more interesting adding a balcony that comes out of the building like this:
I feel like it would add and interesting perspective when the camera pans.
This week I was able to model all of the front part of the building and for next week I will startd modeling the back and the side of it.
