Advise on best method for casting my model

Hello, first time poster here.

I’m looking for advise on how you would approach making the mold for this model. The cast will be pewter, so I’m using Smooth-On Mold Max 60.

Definitely a two part mold, but how would you approach it. I considered 3 sides and 3 sides. I was concerned about some of the undercuts and Mold Max 60 being not very flexible.

Any tips or advice is very welcomed.
