Thanks guys. The masking is a bit tedious especially with a long delay before it's removed. Being patient with it is critical. I just started adding some of the markings in pencil like the studio model. It does replicate the look in the photos pretty well but still looks odd up close. The pencil smudges pretty bad so I'm going to have to hit it with dull coat every few lines to lock down the graphite and prevent finger prints from getting all over it.
