Oh! Speaking of eyebrows, what about making blond eyebrows thicker for a male character? I'm cosplaying Zell, and I have blond eyebrows, I just need to know what I should do to make them thicker? 
I would get a brown eyebrow pencil and fill in your eyebrows. After this, look at your character. Since it's a video game, obviously they look nice and neat but if he was a real guy would they be a bit out of whack and wild like most guys? (Some guys have pretty nice brows but most are just ugh.)
If you want a smooth look, just gradually outline your eyebrows little by little with the pencil until you get the desired thickness.
If you want a bushy look, take the pencil and kind of draw wild lines. Don't go overboard! Just like a few little lines to make it look unruly. How many lines you do changes the style of the look. I would say to practice in your bathroom until you get the desired look.
So, put on your wig and do all your make up and then do one eyebrow one way and the other the other way. Cover half your face and look at one side then the other. See which you like best then wash off the side you like least and try another if you have another option.
