I like it, too. Really dig the tones a lot. Honestly, I like the noise in here, I actually would have guessed that you added it in post. Of course you know you just opened yourself up to a bunch of wise cracks about Nikon and their noise, right?
Really nice! The tone, texture and composition create a romantic feel which highlights the beauty of the subject perfectly. I can't ask for more than that!
I think you probably like it because its GORGEOUS. Not all great photos are technically flawless. Most technically perfect photos aren't nice to look at
