In my opinion:
- Fix the JS error on your site.
- Remove any unnecessary animations like the moving icons from the left/right side.
- Don’t justify the text alignment in paragraphs as it can cause inconsistent space between words. Just use flush left.
- Avoid using hard color on the button borders.
- The style of slider bullets can be improved.
- Make all the buttons consistent in the proportion of paddings, font size, for example.
Hope this helps.
