ON THE CIVILIAN:
Solid!
ON THE KNIGHT:
Right now, her powers are binding powers, and binding is the magic field of Saturn: watchers, binders, death. For this reason, I think you either need to switch her completely to Saturn, or you need to redefine her powers in a way that relates more to the beauty, passion, love theme of Venus. We are trying to have the divisions between Knights be as clear as possible! So there can definitely be an element of binding in her revised attacks, but if she sticks with Venus, the main magical component should obviously have something to do with either beauty or passion or love.
Full-on binding magic is also tricky, though you do a nice job of putting drawbacks on it. But if she bound someone, what would stop an ally from walking up to that trapped person and just killing them with that one hit? I know this isn't something that you would do, but because it is a possibility, I would suggest a less total binding at the squire stage. But, as I said above, I think you should change up the powers if you want to keep her with Venus.
Your Knight attack is a little confusing to understand for me. I know you wrote it out to explain it fully, but honestly, I just got lost in a sea of words. If you switch her to Saturn and keep this, I would really recommend simplifying it.
I hope that helps!
