i think that looks really good, but i have 2 questions, why are you using an insert guide for one of the cables as opposed to just using the cable stop itself? and the brakes levers, aren't they the non V brake version of the lever? m737? as opposed to the V brake version m739? and if they are m737 aren't they spongey?
other than those questions which i guess they'll be a sensible answer anyway i think you have done a really nice job on that. i did a similar-ish build on a 95-ish P7 where the nickel was rough, ended up selling it because i also had a mint nickel p7 but the those style frames in white look really classic and clean
