I got some problem opening up the link until i opened it on my phone.
Anyway, just my 2cents worth of opinions bro! Your hair is definitely thick. If that amount of hair still not enough, i think those with thin hair will surely scold you behind your back. LOL
GD is not suitable for this hairstyle as your hairstyle is really those kind of anti-gravity defying. I think you should shave your sides and trim your side burn. The sides are really too thick, to be honest. U can also consider thinning your crown area and try out different hairstyles too. The crown is too thick too, i feel. Lastly, if you can add some color to your hair, i think you will be looking very good.
When i see your hairstyle, it will be better if you can reduce the shine for this. This kind goes better with matte finish. As honest as it is, i highly recommend you to try out EBL Head Color hair clay.
