Something for Mum & Dad

This is what a business in Australia was looking for in their tattoo design

I have tattoos for my kids, my dogs & my siblings but currently nothing for my parents. I have a star colaboration on my left bicep roughly in the shape of the southern cross, this has my 4 siblings & myselfs initials inside.
Im struggling to work out what to add to this for my parents
A lighthouse rising up thru it & shining the guidance light thru life
Some solar system rings surrounding it with the sun & moon etc showing the way & circling us, they gave us life, guided us thru etc
A large overhanging tree shading & covering
Im not an artistic person at all & im happy to have any suggestions thrown at me
Happy with a bit of colour & happy with B&G also
Not sure if i should put there names, initials, the words mum & dad or just something symbolic
Please help Read more
