https://sta.sh/2as9yt3j28d?edit=1I did some research and modeled her after the Iberian wolf, the native wolf subspecies of Spain and Portugal. You're welcome to change her species as you please, I just wanted an additional callback to the country of origin.
I was struck by how the inside of the church is lit up with rainbow colors throughout, and wanted to represent that, with the subtle colors along her underside. Her left side, much like you had in your draft, represents the "life" entrance, while I took the liberty to make her right the "death" side- her crown fades from life to death appropriately, and I loved the dramatic columns outside the death entrance, so she shares some of that design on her right fore leg. I also noticed that the reliefs on the death side included animals- birds among the roses, so I thought she may like a little dove companion

Additionally, I left my layers all intact, so if you decide this is the design you'd like to go with, I can make minor edits for you.
