Very boring.
I'll go easy on you since you're barely starting, but i speak truth. :P
It was way too boring, I mean, there was little no interaction, aside from pressing the syringes (sp?) and mixing the... mix. Plus the drawings and little animation there was were pretty horrid, way too simple. Work on more complex stuff next time.
Also, try to make things interesting. Add music, and perhaps having made it an animated movie instead of a "power points presentation" (because that's what it looksl ike) would've made it much better.
Not trying to put you down, on the contrary. Cheers and keep it up,
Blaze.
