I've entertained myself today by retouching an image in pixel level. I'm doing dodge and burn with curves and evening out "discrepancies" while being zoomed in all the way in until I just see different tones of grey pixels. This is pretty mental but it's my new favourite hobby. You could do this forever and still not be done with it.
You've done a great job and you're right... the devil is indeed in details. I am renovating my apartment and now this quote really makes sense.
I'd be so shit with renovating, I don't have the patience to be careful with paint and getting everything just right :P
