Firstly well done for posting :hug:
I have to agree with Min i'm afraid. Having the smile line like that makes the nails look stumpier and also a little like onycholysis.
When you file them rounded you need to make sure that you have left the sidewalls in til past the point of the finger and just round the very edge, the way they have been filed has left them with hips.
If you take your file under the free edge and tilt it up slightly as you file this will remove the corners of the tip and not the sidewalls. Removing your sidewalls reduces the strength and increases the chance of breakages.
Did you cut in a saddle on the tips as the index finger on the top hand and both pinkie fingers look like they are slightly ski jumping. I did not use a tip. I sculp them. The pink fingers were the most short ones and most difficult ones. A saddle will stop the bulbous skin pushing the tip up and away from the finger and make sure its fits snuggly, if the client catches these nails they will probably break off.
Just a few minor tweeks and the next set will look beautiful :hug:
That being said I bet the client was pleased with them as they must be a vast improvement to her original nails.
