Well, I'm back in The Sandbox, but this time it's because I need some help. I'm doing a vector from Nagisa Furukawa, the main heroine of Clannad, using this scan
The vector, as it is now. (The original is bigger, though)
I don't know how to do her eyes. I would love to be able to reproduce the "gradient" from her eyes. It's smooth, and it's kind of important for me, too, as it is one of the things I love in Clannad characters design : those big, lively and colourful eyes. I tried many things, but I can't find a way to do them as I want and didn't find anything on Internet to help me.
So, I ask : how can I reproduce the gradient in her eyes ? I really don't know how... and after 16 hours of work, I don't feel like giving up on that one. So what techniques would you use? Thanks in advance for your time and your help!
EDIT : Oh, I forgot... I use Photoshop ;)
