I think some of that is the photo.
According to the iphone level seat tube is 71deg, headtube is 76deg. I'll check it with my digital angle finder soon. BB drop measures 45mm.
Didn't really copy an existing frame as such. I measured the downtube/seattube/chainstay angles on my Pompino (as it has a track legal bb height) and used that info to choose my bb lug. I have that red book I think you had posted in your thread and it has tables of geometries so kinda went from that, did a drawing on bikecad then took that into CorelDraw to check the angles would work out.
I knew wanted a track legal bb drop and the bb lug sort of fixed some of the angles. I suspect I've been worrying about maintaining that track legal bb drop and have 'pulled' those angles a little bit.
According to my original drawing I was going for a 72deg seat tube angle and a 74deg head angle so I'm not too far out.
BB drop was meant to be 50mm, some of the reduction in that will be down to the track ends I've used.
Stem was just chucked in there to get it rolling today, it needs to be longer. I'll probably buy something just now but I have got some of the materials to make a quill stem, I just haven't quite figured out the design yet.

I notice you’ve got nearly no bb drop, quite slack ST and a short stem. Did you copy the geo from another frame?
I’ve picked a 1 1/8 HT and zona tubeset in the hope it won’t be like wet spaghetti
