to be honest i dont think a hawk would suit you..
but i do suggest growing your hair out and keep it kind of like its styled in your pictures but a longer front and tall libs in the back. i think that would look great with your face shape
You could always just give it a shot without actually shaving any thing at first. You could just really slick down and back the sides while having the top spiked and even leave chelsea bangs as you like. It'd give you a pretty good idea without having to totally jump ship to get started.
i was worried about it to for my fist one then this chick i knew told me to not be a pussy and do it so she cut my hair and i fucking love it, id recomend a chelsea hawk but do what was suggested and fucking try it first, then if it looks bad kinda layer it and get spike a bunch of liberty spikes, but keeping your bangs should make it look good no matter what shape your face is.
