I'm back with another bit of feedback.
Flying is an extravagance, which again, subtly suggests that oil is very much a rare commodity in this TL. Computerised design also appears in its infancy, despite the fact that the GPO (and competitors) have computers and t'internet in households, and there's a mobile in every pocket.
Laura grew up eating, and disliking, Woolton Pie? That's a turn up for the books. Again, it's not a point you ram home - it's just there, and lets the reader understand the significance of that tiny little statement. There's some lovely worldbuilding again, hints about changes on the continent, a European Compact, Amsterdam and Paris. The suggestion that Henry went to Durham university is clear to a North Easterner, seeing as I can see no other earthly reason why he'd be living in Pity Me.
Seeing as I promised useful feedback, I'll go with a negative - the only one I can find. The only bit that felt a bit off was the Reichstag photo, the set up and internal monologue on the point. Probably more the former than the latter. The fact that it's Tommies in the image is an important point to get across, and it's co-option by Right Nationalist groups sadly inevitable. It just felt slightly heavy handed compared to the rest of the post. It's difficult to explain what feels off, but it just comes across as a bit clumsy compared to the very nuanced work in the remainder. Oh and there's a "lass" that should be "less" in Henry's revelation that he chats to his old chums on Linkwise.
Thanks again, Geordie – I get what you mean with the Reichstag photo, it's one of the things I'll rework in the editing process.
I really appreciate you doing this, it's a massive help and deeply gratifying from an authorial perspective!
