I hope you don't take offense. I think at this point you are not going to see more coverage on the cheeks. Luke Adam's beard above is about your time frame now. If you continue the untrimmed path to 13 weeks you will see more length in the areas you have growth now. With all beards, what we define as what we like and can tolerate is a personal choice. My opinion is what it's worth which is an opinion. I would go ahead shape your beard to a style like chinstrap with a mustache or a van dyke. As others above have mentioned you have a good stache and chin growth. To me those are very important features and the cheeks are minor. Cheeks don't make a beard. There are many parts to a beard. You are nicely bearded now and can refine your look if you choose to. Good luck.
