I usually let mine hang whereever the hair wants to fall. OR becasu emy hair is two different colors( so one side of the mohawk its radioactive grren, the other a dark purple, makes it so my mohawk looks different on each side) i comb it over onto whatever side color i want to show.
my hair (not to be cocky) actually looks fine either way its pretty dark when not collored and its thick but my 'hawk is longer than yours and it looks fine down since its straight but i just comb it up like shaping the hawk and let it fall and leave it like that
Mine's gone sandy blonde lately. When I wear it down I centre-part it and let it flop over the sides. Kinda makes me look like I'm from some boy-band or other.
