thats mental.. i hate when people do that CURVEEE and RGB mask shit... alll u have to do is make a new layer color over the eye whatever color u want.. and change the blend mode to color or softlight or whatever.. and lower the opacity if u want.. my god
i tried this myself and it looked fake to me. its just my opinion. i prefer to use a softer brush so that it blurs a bit more, and so the white isn't so strong so that it looks a bit more realistic. it still looks great.
sry but the glare on the eye looks extremely fake. you should have set the hardness to less and used a smaller brush imo and gradually make it bigger until you get the right effect. still this looks REALLY good imma try this out next time i'm messing with eyes.
