hey chick, these are overall very nice, and I'm sure your client is delighted!
I can only suggest a few things to improve them:
using an opaque pink - this would allow you to 'reshape' and lengthen the nail bed on the shorter nails (especially the pinkie)
The thumb is a great proportion of pink to white - I would love to see them all looking this balanced...
Also this would allow you a deeper smile line - you start at the right place on the side wall, but with an opaque, you would be able to come further down (again, this extends the nail bed length...)
The only critisism is the sidewalls - they are not all straight and lined with the finger (most noticable on the index finger) they seem to follow the nail plate growth instead.
When filing the sidewall keep the file in line with the finger rather than the nail plate, this will improve their 'straight' appearance...
Also when finishing, ensure you bring the file right down to the sidewall edge - currently there is a square edge down the sidewall (you can see this on the thumb) This should have a nice taper so you can't see where the product starts/stops...
