Yes ,you need to work on your website speed as I am also seeing it is very low. It is 28%. Low mobile page speed may kill your traffic and affect your conversion. Your google page mobile speed score should be above 65-70.
In order to Improve website speed we need to:
-Remove unnecessary code on a high priority basis.
-Compressed images or Defer offscreen images.
-Web Pages need to be Minified.
-Reduce JavaScript execution time
-Minimize main-thread work
-Beware of excessive liquid loops
-Decrease thumbnail image size
-Weigh the benefits of installing another app
By fixing these issues, your website speed score can definitely improve.
If anything is missed out or unclear then don't hesitate to ask
Thank You!
Since Google Pagespeed Insights only simulates speed (which means it's basically just a guess), you should try using a tool that actually gives relevant advice for Shopify sites (learn more here: https://speedboostr.com/google-psi-for-shopify/).
When testing on real devices and real networks, on a standard LTE connection the site takes 4~5 seconds to load, when I think it's possible to get you down to 2 seconds.

The best advice I can give is to go through the theme and add lazy loading to images across your site. This will have a notable impact to speed due to the large volume of images on your site.
