Projection Master, Sebastien Legrain, brick placement ?

ZBrush Usage Questions

Sebastien Legrain did a ZClassroom tutorial about using Projection Master to make a Victorian building:

I want to use the same techniques, I hope, to duplicate this:

This is just an example, though. I need the freedom to recreate any complicated brick pattern and will have often only pretty distant reference photos taken at weird angles. Any advice over and above what is shown in the Legrain tutorial as it applies particularly to my projects, especially placment along arcs and other places?

Thanks.
