Help with a concrete stamp

Hello Folks,
I have been asked by my son to make a concrete stamp.
I am thinking 1/2” deep?
Here is the link to the project.

Any thoughts on bits and process?
I am using a hard wood, an I am thinking a 30 degree or 15 degree bit?
What are the thoughts of members of the group?
Thank you in advance.
Martin

I know nothing about concrete stamps but I wonder if you can do all that detail in concrete? It got me wondering.

Wow!
Thank You!!!

If you need a lot of detail, you might consider using a laser to mark a ceramic tile. That might be embedded into the final product.
