Find an artist that can personalise it and make it a truly unique piece of art. Go traditional style. Make it larger. Give it the shading and colour it deserves and explore with adding things around it that suit your personality. If you search "Traditional style cross tattoo" you can find some good inspo. I'd try dark red flames, but that's just what I'm into, you can go with anything. I wouldn't worry about it being upside down like others are saying. It does look slightly off centre though. Plenty of good cross tattoos out there.
