How to Draw Sara Shirabuki's Eye

I told you I'd do this next, didn't I? Now, this is actually harder than a make it seem. Sort of. What I mean is, I'm showing you the easy way; the way generally used in fanarts. The way I draw it is the original way; the way Hino-sensei draws it. I wanted to tone it down so it wouldn't take too long on a laptop. I usually draw it line-by-line, but I usually draw it on paper. By the way, does anyone know a good place to get copics? Because I need some. I'm trying to do some colour drawings and Hino-sensei uses copics. So they're probably really good. Before I forget, if you don't know who Sara is, she was a manga character.
