Yep. It's not really possible to lighten the wrist outcome without some laser work 1st.
The ankle could be reworked and added to to make it more crisp overall.
Finding the right new artist for either case is paramount.
You can’t cover thick lines with fine lines. Find a GOOD artist (or two) that does coverups and get a consultation to find out what is possible. With tattoos that dark, you’ll probably need some laser sessions if you want something light and feminine.
Choose wisely or you’ll wind up making it worse.
