yep looks like a lionhead x to me too ..he is lovely
the fur on his back where he is moulting..some bunnies do get bald patches when they moult and you may already know this so apologies if you do..but if the skin looks irritated or dandruffy he may have mites..so take a look if he has a thinning patch..and check his ears too as it is probably the photo but they look a bit red inside :? again apologies if you know this and have checked him but better to be safe than sorry
