For me the details are the icing on the cake of most model projects. They can easily be the "how did you that?" Factor that draws viewers in for a closer second look.
Moment of hesitation at the cutting of the cake you risk not getting a corner piece as any one can tell you is one of the four pieces with the most icing.
I'll be honest I was not a fan of the two tone paint on the car until you matched it to the boat paint scheme. That really tied it together and solidified the overall theme. Very nicely done.
