I would also like to add something that can't be stressed enough. reference reference reference. You don't know that you are doing something wrong because you can't see it. Thats why you are asking for a critique. Well, it doesn't always take a taxidermist to see whats wrong with your mount so don't be afraid to ask friends or family to take a look at it and give an honest opinion. Heck ask a random person walking by your house if you have to but use reference
Great pics, Bobbi. Can't help but be a help to novices.
