Responsive landing page using bootstrap 5.2

When I saw the challenge again, I noticed that I was supposed to use position properties for the background svg but I didn't so I wanted to know what would have been the best way to do it.

Also, it is my first time using bootstrap for a challenge, so I feel like cheating lol, so, should I have done it with pure CSS?

I believe I did all the semantic HTML, alt on imgs and the accessibility ok.

It took me around 20-25 hours to complete it, was it too much?
