Alright,so I'm trying out a New Style(for me) which is Vector.
Because this is my first try at Vector,I really have no idea. This is what I got so far,which is almost nothing

. Just added that Red Line,which for some reason I love where its placed. *Update* Added a orange "curve" brush for "flow" considering the guy is looking to the left.

I'm trying to find something I can add. I tried to do those curvy arrows but its so damn hard and my Pen Tool "auto-correct" into sharp lines

Any suggestion on what I can add to make a decent Vector sig.
