>>5884626not a bad start, but gesture drawing involves using lines in a more abstract way. try to draw graceful, flowing lines and use as few as necessary to convey a cohesive image. rather than trying to pinpoint the outlines of the forms like a typical drawing, you want to lay down strokes that guide the viewer (and yourself) to where things connect, fold, change direction etc. and there are no rules about how you go about that. gesture lines don't necessarily depict the edges of the form, they simply IMPLY where and what the form is and how it's oriented.
look up Glen Vilppu sketchbooks and lecture videos. you don't have to go through all of it, just look at his drawings and watch him draw and try to absorb the approach. as he would say, you gotta take and FEEL.
