To be truly honest, I don't see where there is much you can do now. Your beard looks very tidy to me. Your mustache, as you comb it to the side and maybe even use a little wax or hair gel on it for now might help, but personally I don't use it. You are looking great. In my opinion just keep on doing what you are doing. Your photos will be fine. You are grown in well enough, you look bearded and clean.
