May I get a second eye on these numbers?

This is the first frame I've built for someone else.
May I get a second opinion on my geometry?
It's going to be used for centuries/brevets and the like.

Head tube angle: 72
Head tube length: 115 mm (saying it will fit--using an integrated head tube)

Fork rake: 45 mm
Bottom Bracket drop: 80 mm

Trunk: 26
Forearm: 12
Arm: 24.75

Thanks Dazza.

Are my numbers that far off? Damn.
It's not a sale, it's a gift for a close friend who knows I'm an amateur.

But to answer your question, no I don't.
Before I would even consider hanging out a shingle I want at least a dozen frames on the road, 5k+ miles on a few, and a couple professionally tested to destruction. Putting someone's health at risk is not something I take lightly.

I miss typed, I have it marked as 31 inches in my drawings.
And since I haven't cut any tubes yet I think I'll start over.
