How to draw realistic fur and whiskers using the RateMyDrawings java drawing tool. These steps and processes can be using in other drawing tools also, and also to draw human hair.
Once you have chosen a reference picture you need to block out the main colours using the pencil and fill tools.
Then blend the colours together using the airbrush tool in the direction of the fur.
Next add the darkest colour - black - to the fur, in the direction it is growing.
Use a pencil tool, thickness of 1, and very low opacity 40-60, and draw the fur with lots of medium to short length strokes.
Once you have covered all the areas that have bits of dark fur in, then you can start to add the lighter shades.
Make sure to use lots of layers so you can alter lower layers if you need to.
Next go over the whole picture with varying tones, those that match your reference, to give it a mottled effect.
To do this use a air brush on brush size 3-6 and an opacity of 50-70.
Use short to medium length strokes and make sure you can see the dark lines from the last step showing through.
Use a range of colours, as fur contains lots of shades of many different colours, add very short thin strokes.
Using the pencil tool, at a size of 1, and a low opacity 50-80 build up the colours with light shades first.
And then add low lights of dark shades, with the pencil tool, size 1, with a much lower opacity than the light colours, 30-50
And then repeat this till the texture of the colour is like your reference.
At any edge of the animal where the fur is over the background:
First make sure the edge is blurred with the air brush tool.
The using the pencil tool on a really high opacity, 190+, size 1, scribble along the edge as shown in red.
Next using the soft eraser on a low opacity 20-50 and a big size, 20-30, erase the lines along the chin in small circular motions to get an uneven edge and a smooth blend to the rest of the fur.
This make the hairs at the edge have a translucent feel, to be more realistic.
Next use the curved line tool with the pencil tool, on 255 opacity.
Size 2 for thick whiskers and size 1 for thinner ones and stray hairs.
Draw a line per layer, so that they don't interfere with each other in the next stage.
Use the soft eraser at a low opacity, large size, to make the whiskers translucent at the end and opaque at the base and also cone to a point.
Repeat steps 8 and 9 for all whiskers, making sure it is one whisker per layer, or you could end up making some of the whiskers too pale.
Finish the picture by adding the other bits.
Make sure to add fur around them so the picture is seamless.
Refine by adding small details to make it look really realistic always referring to the reference.
