Your beard is looking solid dude I think you should set aside your trimming tools and give your beard a good 2-3 months to grow out. Hair grows in cycles so some areas will grow faster than others. For these first 3 months it's important not to trim, besides neckline which you've already done well, because things may start to even out. I definitely think you're capable of having a youthful looking full beard. By that I mean you can have the full beard look but it may not grow in as thick as it will in the years to come. This helps give you a younger look which is good for ladies (;
