Horses manes (update)

[Ceph]

Are you using photoshop? If so try using the burn and dodge tools with a slightly thicker setting to make the mane.

It's hard to see on this picture, but I did it here a little bit...if you go over it with that dodge tool or with a color over lay you'll add a whole nother layer to the hair, and it will give you some more thickness...you can also use a colored paintbrush with a lower opacity to give you that same ghosty look.
