Hey Christie... Nice pics... thought id post some notes...
The form (silhouette) in pic #1 is pretty nice... and your smiles are more so. The line of light is pretty consistent and well placed.
Here are some tips on pic #2 (though the angle on the index finger is a bit wacky)
#1 This angle shows 2 subtle apex's:
I would economise and merge those babies into 1, smack dab in the middle of the nail (from cuticle line to free edge line)
About so:
So it looks somthin like:
okokok... now the apex is touch too far back now... but im sure you get the point!
As far as the 'bringing in the sidewall/lower arch' thing... this pic show right where the prob is... your Zone 2 to 1 bubbles a bit. If you look at the line of light.... it starts to curve upward from Zone 3, then it gets wider and goes downward as the line moves to Zone 2 and Zone 3.
The line should really stay the same width for the length of the light.
Filing on that line should begin to straighten it out... and debulk that area.
As far as pic#3... They are only slightly thick on your C-Curve... but moving the apex should adjust that slightly.
Thanks for posting the pics... hope this gives some insight!
