Here's an update on the Rihanna image I made awhile ago. Please not that it's still a work in progress as there's still a lot of detail missing.
@Ariel
Thanks!
If you'd look closely, those are the same hands from the green tea lady image I posted earlier. It's quite difficult for me to create hands so I've made a copy of them and placed them here to save time. I'm adjusting them right now and I'll post the results soon.
