My first After Effects project I did by following Digital Tutors course "Bringing Photographs to Life with 3D Layering in After Effects". The tutorial is really great to learn intermediate tricks with AE. Took me around 2 weeks to finish. I must admit I am a bit shocked how much work it takes to create just 10 seconds of animation! I should probably do a little intro and closing to make it look more finished, just didn't have the patience for it this time ;-)
