nice! though the guys who pioneered the process had a step you may have unintentionally missed. see the black paneling? if you grind those areas down a little more with your dremmel, you can cut some black craft foam to the correct shapes and glue it over, to get rid of the inconsistent rough texture there.
good work being a blue shep! i've not seen anyone tackle that color before, and it's awesome to see a more unique color rather than grey!
