It is a little overdone in places - I might tidy up another night. She certainly has a skinny waist and some of the pencil work is kinda rough when you zoom-in. I might try and 'ink' it or play with editing the sketch layers to fix that up a little (areas like her chin maybe).
I will have to try my tablet for this next time round and try some more effects particularly on the fabric and lighting side.
Read a nice article on Volumetric lighting in the ImagineFX mag by Henning Ludvigsen. The bits about the transparency of skin is very nice. I even say some beautiful volumetric lighting coming into the airport tunnel today - sweet. I will have to give it a try next.
