As has been said, at the point where you feel roundout should happen, keep your eyes on the end of the runway and use your peripheral vision to monitor the last couple of feet and the runway edges. With power at just above idle, try and keep the aircraft at a couple of feet off the ground, it will settle on its own, generally with pleasing results. Variations will be learned with experience to account for different weather conditions, runway widths etc, but it will click eventually.
Best of luck with it.
