Very nice indeed, moorsey. It looks very stylish and tasteful. The colour scheme, silver components and finishing kit all look just perfect together. You clearly had a strong vision of what the bike should look like when you chose the paint scheme and parts, and it looks like you have executed that vision flawlessly.
The only problem I can foresee is that such a bike demands that the rider be equally stylishly and tastefully attired, and it may not be easy to find the sort of kit that would go with such a bike, since ideally it too needs to be classic and understated in appearance (although a plain white jersey, plain black shorts and white socks would be perfect in summer).
As for the comments about spacers, I think you have chosen correctly. The suggestion that there is a definitive correct bar height which will never need to vary is ridiculous: it’s not unknown for pros to ask their mechanics to change the number of spacers during a stage race. Slammed stems neither look good nor are they good practice (manufacturers like Trek insist upon a minimum amount of spacers to reduce the stress on the steerer). As for high rise stems, I fear that there is simply no hope for anyone who could even think of fitting such a thing to a lovely bike like that.
