Working towards animated shorts (or other forms of art-driven story telling) takes many facets of discipline, craft, and focus. I find it immensely satisfying being involved in the process, and even more satisfying when DRIVING the process.
HOWEVER.
One common misconception is that the process/steps/expectations are already laid out for you. Sure, there are common practices that have been proven over time, as well as principles and needs which have been established. But that does not mean that conventional steps are the ONLY way, or even more importantly, the MOST EFFICIENT way to go.
We have seen many big-budget big-studio films come out in the field of Animation, and the ticket sales for the opening weekend have to hit such an incredibly high mark, that it muddles if something is "good" or worth doing again and learning from. This is sad, because a movie can have a large audience and be relatively successful, and then be called a 'flop'.
Thankfully I'm not involved in that realm (yet...), but I think that there are ways to streamline and it's unfortunate that studios have not spearheaded this yet.
I'm not sure I have much of a point on this topic, but I really want to encourage everyone working in illustration, animation, television, film, etc... to do what you feel is RIGHT and EFFECTIVE. Following the steps laid out for you by the 'art of' books can be great, but it doesn't necessarily mean that's everything it takes, or that all of them are even necessary. Often they are slick and sexy and self-indulgent.
Here's a sample of a step in the process of a project which never saw the light of day. But it was really helpful defining a 2D CG driven character by doing a quick digital "sculpt" to help the modelers see the design choices, when they are all 2D feeling up to this point:
This isn't anything incredibly special, but I think it exhibits a step of the process that takes thought more than 'artfulness'. One of the biggest things I keep telling my team is that they are hired to problem solve, not to just paint or draw pretty. Our brains are what fuels collaborative environments to success, and working on a team is a different dynamic than working alone. It's incredibly important to understand that and think in a direction that will get a PROJECT done, not get a cool painting in a book or on your blog.
But I get it - sometimes designs and concepts are just done WELL. That makes them nice to look at. Just make sure you aren't doing your functional production art for the once-to-come ART OF book you may be in. But still enjoy it.
