I try to sketch the eye from the picture I found. Actually, a long time ago, I search Evenescence in google picture and found several pictures. I like one picture, maybe editorial picture with a red eyeball and tears in black.
For me, as amateur sketcher, it's really hard to sketch eye like that. But, I try for many many times. So, finally, I made the picture like this.
Hope you like this for Friday Illustration.
