Hey there Lympha,
I too am making a… thing 
that has fury characters without any fur 
I too initially had the characters with fur, but then it proven to be too much trouble (memory, shading, fur animation, time, etc.) and decided to abandon it completely. With fur does look better, but in the end we need to thing first in the big picture and actually get the project done.
What has proven to work, for me, is model some fur stands, not everywhere, but here and there (3 to 6 should be enough).
You can give a look to the characters in here, may serve you as inspiration.
What I did was:
1- Select two planes from the base geometry, where you want the fur strands, make an extrude;
2- Now select just one face and do a new extrude again followed from Scale-> 0 to make a point.
3- Select the other face, make an Extrude and again Scale → 0
4- Adjust to make it look more furry
By what I see you’re already doing a great job! Keep it up!
