How to draw a gothic window

I really do like architectural drawing even though I don't do as much of it as I would like. There are only so many hours in the day... I've been going through Rice's Church Primer as a way of getting some architectural sketching in and its terminology. I had finished up a section on the basics of gothic traceries and I came across a diagram that showed how a gothic window could be constructed. It's from one of those wordless diagrams from thee late 1800's that shows the geometry and background lines on one side and the completed detailed drawing on the other. This is my drawing of that.

Fancy carved wooden door in Habana Vieja, Cuba

This was an amazingly detailed and carved wooden door that I came across on the main shopping street, Calle Obispo, in Habana Vieja, Cuba. Part of the attraction aside from the ornateness, was how tall and incredibly narrow it was. No grand pianos or sofas are going through that!
