Nice work, I've painted a couple of Continentals in the distant past, one in Regal red, and the other in Old English white, both cars were imported from New York, by a local to me RR/Bentley dealer, and ended up sitting in a RR dealership showroom for about 2 years! iirc both cars ended back in California in the mid 90's
Panel work looks great, but its as much to do about how it feels, shut lines, door gaps etc, thats the difficult bit!
Where are you based?
