Hello,
My last pict, always on Photoshop CS2, with my Wacom A6.
How I worked:
I looked the character of Catwoman in the comics for the cat-like side and costume.
I looked at film of Tim Burton “Batman”, for me inspired by the character of Michelle P.

then I created all my illustration by having with the spirit these references
To draw the woman, I used my face, I'm the model, I draw on Photoshop, while being used to me with a mirror
it's not "photo-montage", or "paintover "
By hoping that you like my illustration.
So long. :-)
