Hiya,
I think your smiles are lovely & crisp, but you need to consider the 1/3 free edge colour to 2/3rd's pink to make them more pleasing to the eye.
You could use the EzFlow HD cover pink into zone 2 to mask out the 'natural' free edge. So, put in your zone 1 where your eye can see is the right area and do your smile, the put a small bead of cover pink into Z2 right up to the smile, and turn your brush around, so the bristles are facing you & brush the pink up the nail and ensure it 'melts' away towards Z3. Then go over this with your normal pink into Z2 &3.
Bring the sidewalls in more - place your file straight up the sidewall with your hand above the nail pointing towards you, iykwim and look at the file - if it's coming out towards the free edge ie - not in a vertical line, you need to concentrate on bringing the edges in, do it bit by bit and keep checking. It took me ages to get it right & I have over filed the edges sometimes until the come in too much!!! :irked::lol:
