The majority of lionheads that you see are not actually pure bred lionheads, but a combination of breeds. Lionheads for breed standard have rounded faces, short ears (similar to the length of nethies) and are small in comparison to a standard bred rabbit. They are 'cobby' in appearance and you can definitely tell the difference between a pure lionhead and a mix. I have four rabbits with lionhead in them. Milly is a lionhead x with a cashmere, She looked like a generic lionhead until she got older and her coat continued to grow and fill out. Phoebe is a 'true' lionhead and Teddy is a show standard lionhead. He moves completely differently to any of my other rabbits because of how cobby he is. Maisy is a mix breed rabbit that has lionhead in her somewhere along the line. If a rabbit has a mane, but also has an elongated face similar to most other breeds then it is a mix. Personally I think they are the best ones to go for, because pure bred lions are prone to dental problems because of the shape of their faces.
Mine def sounds like your description of a true lionhead, infact spot on! I worry about his teeth, he had an eye infection last week and teeth were checked and are fine thankfully, but it was my first thought!
I have a cross lionhead too who is just gorgeous
