First you may want to remove or lower the subsurf as its smoothing your shape so much that it can’t even become as sharp as you want it to. Try possibly adding control loops and scale the tips a bit to get the desired result. I would look at mark sharp/mean creases to create sharp edges, maybe even try the bevel modifier with subsurf off or last on the list.
