Rio

Here's something I've been struggling with for a while, esspecially the hands and facial expression, niether of which I'm happy with, but I'm done for now.
She's another Duran Duran inspired pinup from the Rio video, not any one girl, but a few jumbled together. Maybe I wouldn't struggle so much if I started with more of a solid plan or a reference until I get my digi painting skills honed. What I've been doing, is using several figure references to make up my own poses for an outline, and then shading and detailing from memory, then searching for references when I start having problems. Yes, I like to make things difficult for myself
Suggestions and critiques are welcome, and needed, thanks
