Question about painting the armor


New Hunter
Hi guys! It's Simone from Italy.
I have a question about painting the details and the stencils. I have a RDK V3 kit,but the stencil doesn't match so well for the collar i said: no problem,i'll apply the mask by hand free.
the only thing is that i can't find a good reference. i saw a lot of thread and armor painted but they're all different.
The question is: where exactly the holes match with the details? Like i said,i saw a lot of different works and the details in different position.
Thank you in advice for the help!
