Hi and very welcome to the forums =) Your little girl is beautiful!
If she is a lionhead (pet stores aren’t always correct), she could start developping a mane later, between 6 months – 1 year of age. We have had examples of that here.
As for bonding, it’s normal for a bun to be shy at first, and 2 weeks is a very short time for a bun. Ignoring is actually not a bad thing. Ignoring means she doesn’t really trust you yet, but she’s sensing you might not be so bad, you’re not a threat (buns will run and hide or freeze when confronted with a threat, some buns will growl and box). Plus she doesn’t ignore you when there’s food. The road to the bun’s heart goes via the tummy =) I think you just need patience and let her explore you. Rabbits are very curious and cant resist exploring if the human sits still and doesn’t try to make contact. But it can take time, fearfulness is deep in the genome of a rabbit. They are, after all, the prey animals of prey animals =/
