A miraculous piece of work
I'm glad to see that you incorporated much more into the animation this time around. Instead of staying in the Flash screen you moved onto the desktop which I found very entertaining. Bringing other icons into the fight was a clever idea and the AIM guy vs. the Chosen One was a great fight.
The animation itself was very well done and I would like to emphasize the said adverb. The animation was smooth and looked excellent. The sound fit the work quite well and I don't think music was needed. Simple sounds from the various programs worked well enough. I found this especially amusing because our desktops are nearly identical. I have the same background and programs including the avast! virus scanner. For that, I found an extra sense of enjoyment because it seemed like it was happening on my own computer!
All in all, great work. While I am not a great fan of sequels, I do think this ranks up with your first Animator vs. Animation installment. You added in plenty of features which kept the originality and plain fun in the animation. Great job and keep up the excellent work!
