Ideas, Tastes, Preferences and the rest

Boum - You got a Photo idea in Mind -  not sharp for now but so clear.
Then, you look for it, direct the Model's pose, tests, adjusts the lights, become crazy about details and finally you make it! Great.
Now, rest.
But then, few days after, you look back on it and you don't understand any - You Love it for sure but why, why?
It has just happened to me with this one - Now, I just feel between stupid and crazy...
And you? what this you see here?
