oooh well if I'd actually sat down and worked on it properly instead of putting it off and doing bits at a time ... I'd say a couple of weeks. But as I did it, it took a few months because I'm distracted far too easily.
Haha, I'm watching this on the comp. at school and it's playing more slowly, and I have to say I love the part at the beginning where the amoeba-form splits and the other half just goes spinning off the frame! Its face is just so O____O
haha thanks well from conception till this, about 3 months or so I think ... but that was with me procrastinating and leaving all the actual animation till the last minute. If I actually applied myself I could've pulled it off in a week or less.
