Hi
This looks like a good set and you have a good foundation to work on with a few tweaks.
I'd line the top of the stick tip with the top of the bead so its not digging into the clients head so much which may cause discomfort. There are a few cross hairs too, so just make sure your sections are nice and neat, I find spraying with a light hairspray keeps those pesky flyaways from getting in the way. If I was being really picky I'd say to use a darker bead, just to make them a little more discrete. Please don't be disheartened that I've mentioned a few things, as I said, you've done really well, just a few tips to improve your hair game even further. Good luck hun x
