Shrink wrap and edgeflow

how important is edge flow when you are using the shrink wrap modifier? Its the first time im playing with it and im having to put a bunch of verteces in random places to get the shape i want. the only problem is that its created a REEEEEALLY bad edgeflow.

update… i started again and went about it differently before i applied the modifier. I tried to get the basic shape of the coat im modelling and that seemed to have improved the situation to a reasonable degree. i swtill dont know what to do about the vertices that keep getting snapped to the feet though. i dont want then any where near there
