I am trying to output a particular Sketch render but failing miserably.

What I am trying to achieve is an output of a character where there is a complete outline, and complete black lines for the object's jawline, eyes mouth etc.

I've tried different sketch perameters in the Sketch Designer window, such as turning off hatching in 'objects' and lengthening stroke and density in 'Edges' but the best I come up with is the example here.

Is it possible to get clean lines for the complete outlines and for facial features?

Cheers MIke.
