Wow, that is some really cool animation. The moving elements from the original are looking very convincing. And you did that in After Effects? I should play around with something like that as well. Looks fun.
This post would have been perfect for the #creativecoin tag as well. People have been stacking up on it recently because dCity is using a sink for it and many communities here are curating creative posts like yours with it.
Yes, After Effects, I think you'll find it's pretty easy to do. Ideally nice to have the photoshop layered, but there are work-arounds! And just a little bit of simple scripting saves a lot of tedious effort.
A lot going on with Hive lately, I feel kind of bad for missing out, but life is quite demanding, way more than I had anticipated....
