Hmmmm... I think 47 has some potential for the way it somewhat has the shape of a hairstyle. Could you explore that? I think 46 and 47 would be lovely if there's a way to make them perhaps more delicate?
Okay, 46 is still my favorite for its simplicity. You are in my top five!
I don't know if I have any suggestions as I'm quite happy with what you've done. Feel free to tinker should you so feel inspired, but I'm finding that less is more.
