With respect just my personal opinion your template has issues as like premuim design lack, spacing issues in section to section and also spacing and alignment issues in design elements, typography & visual hierarchy, font, hover is looking odd. you have to provide unique aesthetics design, more clean design with proper spacing.

which is best for me now can i improve this design or want to make new one

as it is hard rejected then definitely better to create a new one.

Thank you so much for your valuable time, we appreciate your suggestions and hopefully, we can do better than this, just one more thing I am confused about PHP script like can I use the purchased HTML admin panel for my next PHP script ?? is it applicable for codecanyon

you have to take written permission from the html author.
