Adding the details creates definition and makes your cat come to life. When adding fine details its important to remember to let the first layers of paint dry so that the colours don’t blended and you get clean lines. Unlike when layering tones of brown for the fur this can be done wet on wet and the colours will blend slightly giving a nice textured look.

To add the features use the flesh tint colour for the ears and mouth area. Then add a little vermillion red with that for the nose.

Then you need to add the highlights this builds up the fur details and whiskers. Make sure you are using a clean and dry brush, use the white straight from the tube keeping it pure not letting it mix with other colours. Using a small brush with a steady motion to create the fine lines of the whiskers. If you are not very confident with your brush strokes then you can always use a fine tipped acrylic paint pen instead, this will give you more control. 

Lastly for the extra fine details add in the black sections such as around the eyes and mouth. Use a size 0 round brush and be very soft with the pressure applied making sure you are not pressing to hard, this will help to create and ultra fine line. Or again you may find it easier to use a Fineliner pen. 

Tip- If you make any mistakes acrylics are forgiving, you can leave it to dry then paint over the area. If you are covering up a dark colour with a light colour this might take a few layers. So be patience when waiting for layers to dry and remember practice makes perfect it might not turn out perfect on your first attempt.
