I’m not sure what you mean by construction here?
If I’m inventing a pose while doodling, it’s often very difficult. A 100% invented pose with no reference is just hard. A pose where I have some reference but I need to invent or fill in details is still hard, but less so. A pose where I have multiple reference shots is easier. A pose where I have reference shots I took myself and i added reference as needed is easiest.
It often happens when I’m drawing from my own photos that I find a conventional set of reference shots don’t work for what I want.
And if you look at what comics artists and animators say, they rely on having reference. Loads of it. They’re usually not making up a pose or scene out of whole cloth. Plus they usually put in a lot of time in on drawing from life, both in class format and in a more urban sketching format.
Construction is more usually about finding ideal forms in a real thing. Definitely it applies to drawing people but if you’re relying on it for whole poses rather than teasing out how muscles work it’s probably gonna feel clunky and slow and repetitive.
