You've obviously been prepared to put in a fair bit of work on this.  The three dimensional panelling does enhance the kit and lets its character 'come through'.

It's been a lot of work- more than I anticipated to be fair (I wasn't planning on having to completely repaint the kit, for instance).  Basically, it's been a scratchbuild using pre-drawn parts.  I'm not sure I'll do the other three carriages in the kit straightaway, but I'm confident that they will be a little easier as I now know some of the pitfalls to be wary of.
