Nice work!

 Very cool

I'll vote for this.

 Very neat.

i dunno, i really like the color choices. they're unapologetically saturated & pop arty.

 Great piece that could have been way better with one more frame and better color choices.

Very nice. I like this style.

 Thank you, I appreciate the kind words. To answer your question, I use Photoshop (CS2) for all my pixel art/animation.

 This is really amazing work. I love the color pallette you used, and how the clock works. May I ask what program(s) you uesd?
