painting - from sketch

Painting - from sketch,
originally uploaded by dibujandoarte.

today I worked with live model for the first time in my studio, together with my partner and a friend. After they all left I started this painting on heavy brown paper with acrylics then oil. I still have to finish some details and even darken it all, here I've darkened it a little digitally so this is how it's should look after that dark layer.
