Can someone help homebrew an ancestry for me?

I would like to have Ravenfolk (kind of like a kenku) from Midgard converted to DS. I'm not sure what traits to give them and how to give them an equivalent of Mimicry in DS.

My thoughts so far: Sudden Attack. You gain a double edge against targets who are surprised and those who are surprised have double bane on resistance rolls against you.

Mimicry. You gain an edge on tests made to mimic any sounds you hear. Success means the target believes the sound you created was real.

Mimicry: You can mimick any sound you've heard. You gain an edge on Music and Lead tests to perform songs or recite speeches you have heard performed skillfully.

Secretkeeper: Your thoughts cannot be read by magical or psionic means. Any creature attempting to determine your thoughts or discern your motives receive a bane.

Golden Molt On occasion, the feathers around your head and neck are shed and replaced with golden ones. Whenever you level up, you receive a prophetic vision. It may be the location of or path to an ancient treasure, the secret machinations of an enemy, a message from a divine being, or some secret that the world has forgotten. Regardless of the contents, it is always useful to your goals.

Sudden Attack V2: The first attack or damageing area ability you use in each combat has an edge. Enemies cannot take triggered or free triggered actions in response to you or your actions during the first round of combat.

I'd probably drop one of the ribbon abilities.

3 is about the right amount for an ancestry

thanks everyone else always has cooler ideas than me!

Personally, I do my best work when bouncing off someone else. Without your post I never would have thought of these things! (although the first two are just straight translations of the DnD ability, with a little draw steel flavor).

Those were really good!
