Be patient and stay away from mirrors. It's easy to critique things on ourselves that others just don't see so give your beard some time to develop. Also, facial hair doesn't grow at a uniform length on many guys. You have to let it grow out a bit and allow for some slower growing hairs to come in. Give it some time and then decide what length you want to keep it at, whether you want a neckline, etc.
Also, don't make any rash decisions while growing it, especially during the scruffy phase. Think about it for a day or two. Prime example is me the other day. I've been keeping a short, just past scruffy stage beard. I decide on a whim to go back to a goatee, shave right away, get out of the shower and I'm like "WTF did you just do?" In the process of growing it back now lol.
Good luck and I hope you enjoy it.
