How cute are you! I would go with a fun medium coppery reddish brown. Think of a paprika color with a little more of a brown base. I think it would look great against your skin and features as well as give off a more youthful look. This would be great way to add a little umph to your look. I think the choppy cut would really flatter this color as well.
