Hi Don,

> I used some guides as in the attached image. Is this correct?

Yeah, that's fine - you can arrange them whichever way makes the most sense for you.

Some people like to have the images pushed a bit off to the side so they form kind of a box shape leaving some empty space in the middle for where the model will go.

But they're just visual references so you can put them in whatever arrangement suits you the best.
