Full body bust portrait of character generator character?

[Jellicoe]

Does anybody have an example of somebody who made a full body portrait from a character generated Portrait?
I am not so creative when it comes to drawing.
I have tried taking a current portrait bust of a character I made and extending it for the whole body, but the angle the body is at and the proportions are off.
I was wandering if someone has tried this. I would like to use it as a good starting point.

Thanks.
