totally but you can still still elongate it buy doing the top and the bottom.
firstly, line the waterline all the way along, but at the lower lashline, just line the outer third. keep it quite thin (although still soft, rather than smudging pencil you can to a thin line of black eyeshadow with a lining brush). you still need to draw it out and upwards at the edges, joining it with the liner on top.
does that make sense?
