I will never be a Gemma Lambet or an Angel Fingers or a George Smedely.
I can and do admire their work greatly, what they can do with 3d work is breath taking and it's not in me to produce work like that.
But a set of strong, elegant l&p nails, yes I can do that. I will always pick holes in my work, always feel a bit surprised when a client says wow! Thank you and tips me when I've looked at them and thought crikey, they could have been so much better.
There is nothing wrong with seeing the faults in your work, striving to produce better ones that's what makes you a nail stylist instead of a woman who works in a nail bar.
It becomes a problem if it stops you leaping in and charging a decent price to clients. Been there done that, why? Because I will never, in my own eyes be as good as Gigi Rouse. I've never seen her produce 3d work, what I've seen from her is perfectly shaped nails, time after time after time.
But my nails are nothing to be ashamed of and having seen yours, neither have you.
Your side walls are parallel, your proportion of pink and white is spot on, your line of light is pretty darn good.
I didn't see but you said you'd touched the skin, ok, 3rd bead, make it tiny, place it just behind where the second bead finished. Let it settle, hold your brush nearly flat to the nail and push the bead into place, then pat into place before very lightly, light as a feather, pull back your brush, keeping it nearly flat, you don't want to drag the bead up the nail you just want to make sure that the very edge of your 3rd bead is so fine that you can't see where the acrylic ends and the nail begins, that way you don't touch the skin and as the nail grows out you don't get a ledge that you've got to file away for the rebalance.
You didn't ask for a critic, but I gave you one anyway, I'd let you do my nails for me and I'm a very fussy mere, so well done and no, you don't have to be an artist, you just have to care x
