I do not like dropdowns - I got feeling that they are not finished.
If I scroll down, content show too late and for 1-2 second I see blank page …
Top menu “shopping cart icon” looks bad …
That’s for me after few seconds. Overall lack of subtlety … work on typography.
Ps. don’t use text like "blog section 1 " , "blog section 2 " , “blog section 3” … Think about Your demo as an advertise … people must see finished and beautiful product.
