Details about painting animals

I will have to say that the hardest part to paint the animal is to paint its fur. Especially in painting ACEO animals, it required fine brushes and extreme concentration and patient to finish the job. I personally love watercolor. The watercolor is easy for me to get the details. Acrylic ACEO is my dead spot, which needs a lot of practice to achieve the flowness like watercolor. Usually the paint just stuck on the brush and won't let go on the paper >_<

I really admire the ACEO works of a few artists (on eBay) who can paint the details of the animals so fine with acrylic. Again the golden rule... Practice and More Practice! And don't forget the fine brushes that won't have split hair... *the split hair on the brush drive me crazy...*
