I've used Jobst Brandt's book as well as Lennard Zinn's book as my "go-to's" when wheelbuilding. And to a previous comment, no you don't need truing stands, dishing gauges, tension gauges, etc. to build good wheels. Those are useful tools which help speed the process, but if you have your bike, really all that is needed is a quality spoke wrench and a bit of lubricant for the nipples. Years ago, I (re) built a back wheel the night before an event in my hotel room with nothing more than my bike and a spoke wrench. Today, that rear wheel is still on my bike and is true and round.

The first wheel is the hardest, the first rear wheel is a bit harder still. Agree that the OP's lacing does not look correct.
