is this cultural appropriation?

On 11-17-2021 my grandfather passed away. He was my inspiration in life, the reason I have my passions in science and art. On my birthday, ( dated below the picture, ) him and I created a tattoo. Originally I just wanted a skull, but the further we got into it the more creative we got. I thought about everyone in my family putting hidden hearts throughout the tattoo. At the end, to me it looked like a pirate skull.

I’m thinking about getting a tattoo in remembrance of him, but I realized that this kind of resembles a Día de los Muertos, or Day of the Dead skull. Día de los Muertos is a holiday celebrating the deceased loved ones that, correct me if I am wrong, originated in Mexico. It is a beautiful celebration, and a beautiful way to celebrate the dead. As much as I love this tattoo, I don’t want to get a tattoo that’s supposed to be meaningful to me, to upset and offend others.

Please let me know your opinions, I want to know if getting this tattoo in any way is going to be offensive, and if so, I will use some of the other ideas I have. :)
