I really want to make a carnor jax costume


in this topic I am going to post pictures and updates of my costume.
and I start off with this one:
I found a guy who did sell a carnor jax helmet, now my question is: is this a good one? or need it to be changed at things? if so, what do I have to change about it before I am going to paint it

here is the helmet that I want to buy:




for now I am also worried about the undersuit...
I now it has to be lycra/spandex, but I didn't know if this will be alright (and change it to a carnor jax undersuit ofcourse
