i really like the idea and everything, but the drawings werent that great.

Just take your time coloring in the background and you will do fine

the animation was a bit jumpy, the "people" (i think thats what they they were) were jabbering nothingness and their finger flew everywere on the keypad!

i do thoroughly enjoy the ideas and well, y`know...

sorry if i sound like an ass, you asked for constructive criticism.
3/5!

omfg this music is rly terrible DX (i mean, i got two or three music sounding on the background DX my ears!! DX)

the idea is good, i like how you reprecent the immune system with robots... but... i didnt like so much the graphics, you should quit the rough line black? or just... draw them symethrical...

there is another thing, i saw that so saturated, coz the graphics are too big i think... maybe you should make them more little?

and~~ put more action!! i'd wanna see the robots of the immune system, lots of them, on an epic battle, fighting against those dirty bacterias O_O

the idea is great XD, ill put you 6 for the idea (and some graphics... i loved how the immune system "detects" the bacterias)

That a lot of effort went into this. Biggest suggestion for improvement in your work is this: stay away from the gradient colors. Using them like you did doesn't really give dimension, as there is no direction for light source indication when all sides are shaded.

Also, I noticed that there seemed to be a second music track running behind the one that ran at the beginning. I don't know if that was just me or not though.
