Since I'm real new to rating I'm going to just be giving suggestions at the moment.
Avi 1 you could use some red and white on top and black on the bottom to even it out.
Avi 2 needs more of the scarf color near the bottom if you leave your hair black then you need some black on the bottom as well the puppy looks out of place to me( maybe just a personal thing )
Avi 3 I really like this one you just need to add some white to the hair and gold to hair and neck
These suggestions are based on what I have read in the AT
