Hey, I was sweating over making my own unique eyes for a preset... until i looked at my really cute abyssinian kitten!

just took a photo off my laptop of him and copied his eyes, and pasted them on the preset's eyes (only the pupils of course)

I used some blending and a change of a few colours and enhanced the shine in his eyes, and then I think it turned out ok... at least for me because I'm new to presets, I still need to change the colour of the eyelids... just realised XD
