Sure, no problem! Well, from my experience, when painting the mane or tail you should not focus on drawing each individual strand like super realistically. It will make it look very cluttered and sometimes it ends up not looking that well.So, from what I've done is you have to concentrate on knowing where to put the lights and shadows first and then adding a couple of strokes that give the idea of strands. If you look closely, not every single pixel is filled with strands, rather than just a couple of them that give out the idea. Also, study how light behaves in these kind of textures, references are your best friend.This effect is mostly achieved with practice but with that you can make them look better since you're letting your brain fill up those "empty spaces", what I mean with this is let it figure it out it's hair by adding just a couple of strokes that make it come together, so it doesn't look that busy and uncanny.Hope that helps! It's a rather complicated subject but with practice I'm sure you'll get it eventually!
