An Eye for an Eye
Again with the Ellipse Tool and Shift, create another circle. This will be our pupil.
In my case the blending options from the iris were still present, just left click a layer and select ‘Clear Layer Style’ to send it on its way. Fill it with black.
I added a touch of an Inner Shadow as well.
Now to add in some shiny reflection. Grab a soft brush and draw in some white glow.
Add a blur to this layer to dissipate it slightly, and there you have your completed eye!
Here are a few more variations on this technique. Don’t be afraid to share any you have made using this tutorial! You may see it on the site in the future.
