You asked if that's a good edge flow or not, and quite frankly, that's not good, what you want is for your model to follow the muscle flow of the human body and still maintain a good poly count. And at the moment your model does neither.
What I would suggest is for you to look at some already existing edge flows of characters online (
Like here) and also look at some general anatomy studies to get you familiar with how the muscles flow.
And obviously practice. Learning how to model organic things can be quite the fiddle at first.
