Is fawn visible anywhere in the coat (when you blow into the coat, is the middle ring fawn)? If there's any Chinchilla in the background, it could be a dilute Chin, which I believe is called a Blue Chinchilla in Mini Lops.
I used to have a Holland lop buck and he was a lot like my mini lops but he had a broader forehead and might have been a little smaller. I really like Holland lops though!
