I voted for #3.
#5 & #10 are great ones too!

They were all pretty good but #1 the person is still young, her looks could change, #2 I don't think they look a whole lot alike, #4 they have the same color hair but thats about it, #6 looks like a puppy still and a guy who didn't comb his hair both of their looks could change, #7 you see that resemblence a lot, #8 what do they look like NOT dressed up, #9 wouldn't look alike without the makeup.
