Simple as the title explains. This is for thick fur. I do not recommend for very short fur.
1. Start with your flat color.
2. Give your flats simple shading.
3. Define your fir clumps with slightly darker tones. You can even take your color from your mid-shadows to do this~
4. Push the darkness between the fur clumps where they touch and overlap.
5. Add some of your lighter fur color to your darker fur clumps, but softly so. It helps them pop out!
6.Blend out your overlapping shadows so they five the clumps a nice and soft trasition where they are coming out of the pelt.
7. Add even slighter darker points between clumps for contact shadows!
8. Add your rim lighting/shine to your pelt!
9. Notch the fur clumps a little on the exposed edges so they feel like there are smaller strands apart of a whole!
Aaaaaand profit! That is how I do my fur! With markings it can get a little complicated, but you can also do all kinds of scales this way too! Enjoy!
