No, although I DID try that, which looking at it helped to nail the neck MASSIVELY. Looked too clean (oddly something I strove for after abandoning the sketch-up approach).
It was too much trouble using the model as pencils, so I printed it out and attempted it freehand - startiing with very very sketchy pencils. Took too long to get to that version, but I wasn't feeling very well and mostly unable to move so at least it was diverting. Maybe one day I'll get good and/or quicker.
