You, sir, are a genius! This is absolutely breathtakingly amazing! It’s photomanipulations like these that make me want to punch myself in the eye to see if I’m not somehow delirious.
At first I thought it was a photo. It’s so well cropped and blended together, it makes me wanna cry! The composition is incredible! The stock items, very well chosen, greatly enhanced by the softly desaturated colors make me immediately think of Tim Burton’s creepy yet at the same time humorous style. Something I noticed is that you’ve managed to use the shading to your advantage, giving the girl’s expression, already fit for the picture, an even better, more childish and curious look, which is perfect!
As for weak points, I honestly see none. It’s simple and perfect. Easily one of my Top 3 photomanipulations I’ve seen in a while. Great job!
