Sharpie Sketches - Horses by ColossalBeltloop . I once heard an artist say that she liked to draw in pen because there was no erasing, and it helped her learn to accept imperfections. That seems like a good (albeit somewhat painful ) idea!
Norwegian Fjord horse with a beautiful mane! Usually their manes are cropped so the dark hairs form a straight line that continues down their backs to their tails, but this looks really pretty all grown out.
