Desktop First ,responsive, using Flexbox and BEM.

Hey community!,

This is my first Jr. challenge. I spent few hours trying to approach the layout. In this time i tried Desktop First, but i found it very hard to do. Find the right mobile breakpoints was a really hard task for me. I did it with Flexbox , because i still don't learn Grid.

So my feedback request is:

Do you think is normal that it takes me so long to make this challenges? (i mean 4-5 hours. Even 2 days :c ) or I just need to keep practicing to achieve greater skill?. Right now i'm very tired from this challenge and i'm gonna rest a litle bit jaja. ✌️
