it's always a little difficult to build up a classic frame with modern parts. i like the idea of that classic look with up-to-date technology of the components. photography is well done, respect!
however there are several parts that do not quite fit the frame. first of all the stem is way too "fat". i would definitely go for a custom painted lugged steel stem with polished lugs, such as llewellyn (quite pricey though):

the bottle cages and the whole groupset are quite plump too. it's the latest technology, i know, it looks great on a carbon fibre frame, but on this frame with slim steel tubes, it looks a little misplaced/overdressed.
please, do not get me wrong, it still is a fantastic bike. all its components are fantastic if you view them alone. but alltogether, i see room for making the whole build a little more harmonious (= heavier though).
anyway, enjoy your sweet ride and thanks for this great photography! and don't care too much about my personal opinion!
