So i have the question.
I use brighter outlines. Sometimes that give the feel the 3D effect. – So i think for two thing try it out and you see wich is perfect for you.
So my first advice try out a brighter outline for the character. (Maybe lighter black or grey).
2. give a little zypping (shading for that body part wich in front of the sun) (a little white shade is good maybe the transparency is 30 – 25) –
A little tutorial picture how i thinking.
With Shade
With brighter outline
I hope that helps you
