I like the blonde and as you have really blue eyes it really suits you, looks very natural on you. You look softer and more approachable with the blonde hair.
LOL.... are you serious? If you were to shave it all off you'd still be hot!
I am thinking the blonde to be honest. But if you consider the brown, i would go a bit darker. Or you could become a hair model and you get new and awesome haircuts all the time and make money from it
