I personally don't think that your cheek growth is yet sufficiently high or dense to give you a convincing full beard, which is why I suggested the wide chinstrap style which I believe will make the best use of your current resources, whereas letting the neckline drop at this stage will, I think, only serve to give your beard a bottom-heavy look. My advice would be to wait a while before embarking on a full beard rather than rushing into it before you have adequate growth to support it.

Keep growing. Stay bearded!
