Wordpress Blog Theme Rejected

my wordpress theme got rejected, and they say like this : ‘unfortunately we found it isn’t at the quality standard required to move forward, and you won’t able to re-submit this item again.’
here is the demo link :
and here dark mode link :

please give me answer why my theme not meet standard quality.

I am sorry but this design looks very, very outdated. Keep on practicing your skills and hopefully you will get them on the level which is required on this marketplace.

You tried very well, but your design concepts are very old. Please check some latest design from themeforest and get ideas how trendy designs are going. Hopefully, your efforts will pay off you.
