Cute! It was good but...
As far as I know, the American version of this at least (I'm not sure where you're from) you missed the part where the first 2 pigs just wanted to build there houses quick and the last pig took the time to make his out of brick, hence making the moral something along the lines of "if you take the time to put effort into something, the rewards are well worth it!". You basically just mentioned what they built their houses out of, but not why.
That aside though (and even with it missing) this is still very enjoyable and fun! I love the clean lines and smooth animations, the Sepia Tone and music giving it an old timey film style, yet adding a slightly new age twist with the movements and details. I like the idea of a virtual pop up book, but instead of the pictures popping up, they are moving instead. I hope you'll make more of these as they are adorable, and hell, a fun way to show your kids an old classic. Very well done sir!
