In a recent post, I blamed the demise of 2D animated features on market saturation; there were just too many features out there. But in CG land, there are more animated features than ever, with many of the same artists behind them. Are CG animated features facing a similar fate? Anyone who was around during the 2D renaissance of the 1990's knows this is not out of the realm of possibilities.
So what can we do to protect ourselves? As an artistic cog in the production wheel, all you can really do is keep growing as an artist. Try to make contributions that are unique - don't repeat yourself. Sometimes this is difficult, because that's what the people paying you want, but remember - they only know what they have already seen, it's up to you to be creative.
