First step. Try to "weight" this cat, determine the largest parts of it.
Then take another piece of paper and try to sketch the lines that form the lion.
At the same piece of paper add the jube with wide moments "from elbow" using dry brush with black China ink. Make the lines clearer, but they should be not solid, but broken. Make nose and chaps darker with black.
Add spots using wet brush. First add lighter spots, than darker.
If you want to have the same affect of "acient paper", use beige rice paper and add brown mineral color into the ink.
