Advice needed: Tattoo Ideas for My Brother Who Passed Away

I'm a 40-year-old woman looking to get a small, delicate tattoo in memory of my brother who recently passed away. He was a truly kind soul who loved helping others, and our bond was very special to me.

I don't want anything explicit—so no "RIP," wings, or obvious symbols. I'd prefer a design that's simple, subtle, and meaningful. Ideally, it would fit on my wrist and capture the idea that I’ll think of him until my last day. I also want it to quietly hint at the reality that life is fleeting and all about transformation in the end.

If anyone has suggestions, minimalist sketches, or has seen elegant concepts like this, I’d really appreciate your input!

Thank you so much in advance.
