Am I terminating these CAT6 Keystones correctly?

Hi,

I am running my own CAT6 in my house and i got these keystones from PBTech (https://www.pbtech.co.nz/product/ITPFPC6002/Dynamix-FP-C6-002-Cat6-Keystone-RJ45-Jack-for-110)

Below is the keystone + my first attempt at terminating:

I thought i would ask here first before i continue to terminate the rest of my cables if:

a.) The colours are correct (going for T568A)?

b.) Is the CAT6 cable sheath close enough to the keystone?

c.) it is ok for the wires to be untwisted in the keystone (mainly the brown & green wires)?

Thanks!
