maybe we could see a full body pic of her?
that would help us be able to tell better.
from what i can see of the face i'll say this:
LEAVE her mane and tail. arabs and welsh both have long mane in the show rings, so thats not a big deal.
from what i can tell from her FACE i would say trim the legs.
but i would need to see her body, if her body is more arab-like then i would trim them. if she resembles the welsh more, then i would leave the feathering.
GOOD LUCK! =]
You can tell a gelding, you can ask a mare, but you must discuss it with a stallion.
