Astraea Aurora
It's really up to your liking. Do what pleases you.
Although, a warning note:
DON'T use a gold or silver pen, at least not those waterproof ones. I did some golden fine tuning on my Fenestra last summer with the help of a golden permanent marker (the ones that are waterproof and hold onto glass, plastics, overhead projector transparencies) and now my whole deck clings together. There is no chance to ever easily shuffle this cute deck again! There will always be four to five cards sticking together, at minimum!
Don't do the same mistake and ruin your deck.
Despite my warning, have fun alterating your deck to your liking.
