Yes, form looks fine on both. Honestly, after 2 cycles of BBB, you’ll have performed these movements so many times, it will be robotic when it comes to form.
I will say, the more you do heavy OHP with 5/3/1 you will learn how to use your legs and core to drive the weight despite not actually moving your legs. I know that sounds like it makes no sense but trust me. OHP is a total body lift, dont care what anyone else says. Also, lifting a barbell over your head is the manliest thing you can do.
