number 3 is bland, nothing is really highlighted... but the other 3 are lovely. Number 1 is nice, i have trouble getting that effect but number 4 is my favourite. I cant decide if it's a little overexposed but even if it is, it's a lovely shot 
Nice model too. As a man i feel it my duty to point that out.
