I would hate to have to guess any many hours work have been put into the model at this stage, and I doubt I'm halfway through the build yet.
A lot of time was spent very early on in the build making sure that all the decoration etc was going to fit, I can not stress this enough it is far better to spend another week if needed to get things right at the beginning, than have to start taking things apart or altering things at this stage. Before gluing something in place have a look what fits to it or how it effects other things around it.
Take for example before gluing the brass moulding above the windows on the stern I checked to see that the coat of arms and crown would fit into place.
Various close ups of the stern galleries, as with all things on ship modelling there really is no quick way of achieving a clean look, other than patience and even more patience.
The decoration along the top of the coat of arms is actually cut into 2, the slight gap is under the coat of arms so as not to be visible.
