I can definitely write a few words about Tom Ford nail polish formula since I own almost all of their nail polishes.
The quality is not consistent across this range, some may be streaky and difficult to apply. Some may turn out to be very good quality. But I haven't find any of them being close to my favourite nail polish formulas such as YSL, Burberry and Giorgio Armani, Armani being the best and backwards in this order, Burberry's formula is very close to Armani but unfortunately the brush is not that good. Overall I find Tom Ford's quality close to Chanel and Dior, if it is a good one and worse if it is a bad one.
That said, I haven't tried the spring nail polishes yet. I will report again when I do so but the coral and pink ones seem sheer, it seems bloggers liked the nude and the metallic one, yesterday I have seen a good review on Make-up Magpie: http://www.makeupmagpie.com/2014/02/tom-ford-spring-2014-display-images-and.html
I am also waiting for deep down review of Jenny.
