1.the color palette you’re going with doesn’t fit well (yellow and purple) find another color harmony
2.some headings needs to be bolder and bigger
3.there’s little contrast between the paragraph, the heading and the background, i can hardly see them, you need to establish visual hierarchy here.
4.the [read more] button is taking too much unnecessary space.
5. separate your sections with more modern and creative way rather than a block on top of each other.
6. bad use of negative space.
7. some spacing and alignment issues.
8. the header looks clustered and too busy, too much stuff going on.
my advice will be to look at: visual hierarchy, typography, negative/white space, spacing and alignment, and color theory.
after that i highly recommend that you look at the newest templates, see how they arrange their sections and handle their typography. don’t look at older templates cuz today’s standard are high.
hope you the best.
