I would suggest using darker grey (even darker than the hull) for the railing when it abreast of the dark grey hull... unless the railing is indeed supposed to be "gold".
I was going for brass, actually. What is the SB standard color for that?
If you want good set of detail just study other drawings of these era ships and "shamelessly" copy what the others have done
In doing the masts and other odd bits, I extensively used Darth Panda's Victoria and Alexandra as advice on how to shade and what colors should be used, but I didn't directly use anything from those works, hence why no crediting was done.
