work in progress - tiger

Just a WIP picture of a tiger. Honestly, I'm practicing fur-drawing, because it's really hard for me (that's why I prefer birds x"D) - and ummm I got stucked, I don't know how to draw its cheeks, whiskers and ears. If you could help me and find tutorials how to do that I would be really happy so fur-drawing tutorials (of course, traditional art) are appreciated. Feedbacks and advices too.
