Responsive Testimonial section page using grid

What are you most proud of, and what would you do differently next time?

I am most proud of my ability to identify the section colors correctly and to be able to get the structure of the sections right. Next time i would try using flex box to achieve same design.

What challenges did you encounter, and how did you overcome them?

I had a great challenge in figuring out how to structure the sections for large screens using grid. My biggest challenge was placing the quotes image in the first section box.

What specific areas of your project would you like help with?

Can someone help tell me how you figure out the width to set for your main container so that it matches that in the design files? and also how i can fit that quote image to blend in the background of the purple box. Thanks in advance
