Gadot must work consitently on her body to sell she can stand hand and hand with Bats and Supes. Looking at Gadots appearance the actress is more skinny, then athletic in build like W.W. Also maybe not as vuluptuous or curvy but.
Wonder Woman in the comics is a fantasy visually but its her strenghth, boldness, and leadership that win us over character wise.
Gadot must do her best to look like the character as much as possible but. It is her acting and potrayal that really matter.
