Hey Komacide, Patrick is right about the cheeks maturing more later in life. The cheeks are in many cases the places that take the longest to mature actually.
I'm 25 myself and because I kept a photo journal here on this beard board I could compare 24 years old to 25 and I have made quite big improvements over just 1 year!
So don't give up hope because time and a good lifestyle will do miracles for your beard.
Your current beard look great already.
