>>1676381This is what I'm working on right now. As you can see I'm using a combination of hard and soft lines using gradients and blurs.
For instance the hair lines are all solid while the bra and her arm have soft lines because it looks closer to the original image. Even though its not 100% vector with blurred objects it achieves the effect that I want it too.
I think combination is the best over hard or soft on everything.
