Animations are absolutely one of my favorite things to create. It's one thing to create a beautiful illustration. It takes a completely different mindset to set your document up from beginning for moving parts and special effects.
I can honestly say that most of my design experience is self-taught, especially in the animation category. My university did not specialize in much more than layout design and photography, so I found importance early on in doing work outside of the classroom.
There is much to learn, but I'm happy with all that I've accomplished so far and I can't wait to see what new animation styles I'm able to tackle next.
