Making a animated film is easy. All you have to do is write the script, storyboard it, create the concept art, design the characters and environments, build the 3d sets, props, models, characters, texture and light, rig the models, animate, lip sync, render, comp, fx, edit, sync audio, music, final comp, and done!
The only difference between a short and a feature is the number of shots you have to do. Anyone who thinks it's too much of a task doesn't know what they're talking about, because I've done it, m dot strange has done it, Jeff Lew has done it, Matt and Dan O'Donnel did it.
I've never heard anyone tell me that I couldn't finish Archon Defender. Guess I wasn't listening. (too busy making my film)
