Renew Old Tattoos

For my b-day recently my honey pants super surprised me with an appointment to get my feet tattoos touched up. Tomorrow I go consult with the artist, who is also a friend and all around great gal. I want to update my tattoos but don't know exactly what that might look like... Any suggestions?

Helpful info:
- I am one of those people who has a story and meaningful symbolism behind each tattoo on my body (total of 5 so far). Metaphors and the like turn me on.

- I love colour in body ink esp the ones in my feet and have wanted to experiment with white for a long time

- open to partially covering current tattoos, even though I still love them after 10 years or more I am up for some freshness

- visually I'm currently attracted to fractals, old school calligraphy, industrial design especially old machinery and old typewriters. Plus the usual... nature and stuff (tehe) leaning harder toward winged bugs and gnarly vegitation like thistles and unusual plants of dark beauty.

- also whimsy and smart humor I love comics & graphic novels filled with ridiculousness and sometimes spastic characters always able to find everyday life oh so droll... And their use of sarcasm & satire ~ love it.

- The most sought after and potent desire I have right now is to find a worthy direction to move in; one that draws me toward it and welcomes me with gifts of clear purpose and compelling life affirming adventures along the way. Too long I have been scattered, fragmented and tortured by uncertainty coupled with or perhaps causing rapid cycle changes in desires/plans for future both long term and immediate.
I seem to always be on the threshold of some great potential or at a total loss for what I might want to do. Any symbolism that could speak to a strong desire to have conviction and longevity on paths well chosen from a combination of healthy head and magic heart would be awesome.
Tall order right? oops, sorry 'bout that but it is what I'm after so if ya gotz any bright ideas pls do tell.
Spanx;)

- other than the above mix of notions and desires I can say I love my feet and all I can do because of them. Walking is my main mode of transportation, buses and such are mere side dishes. And dancing - who could live without dancing.
