Guess ad with hot guy n girl

this is a sensual ad from Guess n i think the girl is very hot.. i took around 4 hrs for this.. considered quite long compared to my normal speed.. i did the pencil outline manually then scanned into PC.. then colored with Corel Painter 9 with water color, using difuse bristle.. this is a semi finished technique using a contrast outline but realistic colors.. not considered a realistic approach
