Your Mustache really looks promising. Your cheeks look like that they could get better with some more length. Three weeks is still a bit early to really know what is going to happen with your growth. Have you tried combing/brushing the hair on your cheeks in different directions? Changing the way the hair lays can greatly effect the look of your beard.
Your growth reminds me of a friend I had in High School. He grew out his mustache, and all the hair on his neck, but not his cheeks. There was something about the length and density that made it a unique beard, and I couldn't name one person that did not like it.

"How womanly it is for one who is a man to comb himself and shave himself with a razor, for the sake of fine effect, and to arrange his hair at the mirror, shave his cheeks, pluck hairs out of them, and smooth them! ... But He adorned man like the lions, with a beard, and endowed him as an attribute of manhood, with a hairy chest—a sign of strength and rule." St. Clement of Alexandria, 2.275
