I think they are very good and I would pay for those. Just try to get your product slightly more flush at the cuticle on some of them, and also the sidewalls are slightly wonky on a couple, and the length is inconsistent, but all this can be corrected by just going over them with a file again.
The C-curve that I can see is very good.
You are doing very well as you have only been doing nails 9 months. Can I ask what products you used for these?
