Welcome to the board, aj! Your beard is looking great! I would not say that you have 'very patchy' cheeks or chin in the least. I think they look good and you will see that they will continue to fill in over time (if you avoid the trimmers). It looks like you were carving a neckline at one point, but have let it grow now... if thats the case, it was a good idea. It will give your beard more bulk and a better, more natural shape as it gets longer and blends in with the rest of your beard. Looking forward to following your progress.
