If the beard in that pic is what you want, just let it grow for at least another 3-4 months. Don't worry about trimming anything just yet, your beard will change shape many times as it grows longer. Even the cheeks need to be quite a bit longer at this point to get the style you're going for. All you really need to do now is just sit back and let it grow, when it gets much closer to the desired length you can look at trimming. Keep us posted.
