Check Out This Product Landing Page

Hello sir/madam,

Can you please give me your honest feedback on my new product landing page? And which one do you like more the old one or the new one or both?

Old: https://codepen.io/Muallim/full/zgBwdN

New: https://codepen.io/Muallim/full/Qedmzb

Also, can you help me center the navigation menu? I tried margin:auto but it didnt work and I tried a few other things but they didnt work either.

Thank you for your feedback in advance!
