2-hours studies of each mammal that I use to illustrate the diversity of small mammals we have in the world. It is also my opportunity to explore and discover new lines I can make with my Chinese Calligraphy brushes. (I use them because they are cheap and good in Singapore, but they don't last as long as other quality brushes) 

I particularly liked the layering I did and thick brush strokes to make it a little shapey and angular. Mixing thick and thin lines is a good way to show some contrast.

Understanding the anatomy of a extinct animal is hard so I had to follow the expert illustrator's model. I used the dips of ink to show gradual shading of forms and shapes. 

Making hairlines can make the subject looks real because they look like the real thing. Thick to thin is an ideal or simply very thin lines like whiskers.
