flash on acid?
at first I had absolutely no idea what was happening. then i stopped worrying.
First the good: you never seemed totally out of imagination. that is the most essential part of a piece like this. morphs have been done and redone to death, but the good ones always have interesting ways of transforming. several images seemed all to ready to destroy themselves, or explode or fuse or something, which added an amazing "just watch this" kind of effect to the whole thing.
simple imagery. let me explain: when engineers want to say something they draw a diagram, when artists want to say something they draw a picture. similar concepts but the artist's is usually much simpler allowing for easy understanding of idea. Your work exemplifies this, have simple pictures which not only are fun to watch, but make for easy transitions.
Now the Bad. Unfortunately, i have to point out that your artwork itself, while imaginative, was a sorry site. The point will be made that you are crippled by a bad mouse, but at the end of the day it still looks sloppy. But the artist can always improve. it is a never ending pursuit. do better next time.
whether do to equipment issues or otherwise, there is a definite sense of choppy, jerky motion in every frame. The second biggest part in a piece like this is smoothness. this did not have that. Consider the opening morph. the flow of events were correct, but they appeared to either have to few frames for a motion, or the motions flow was arrested due to perceptual inconsistencies.
there are moments where the morph is turned into a ball, and rolls around the screen. I assumed at first that this was just part of the animation, but as it happened more and more it seemed less like art and more like "well i'm running out of ideas". if that happens, as I'm sure it does, having black on the screen is not necessary. if your mushroom exploded, let the parts fly off screen, but bring them back.
also, displaying the cannabis sativa during a session which also looks like an acid trip is likely to confuse the user as to which hallucinogens he took.
Recommendations:
get a better mouse for one thing. if that is what is holding you back, then fix it.
definitely make it smoother. also for some reason (if your paying attention anyway) any and all lines are rounded. if that's how you wanted it, that's fine, but it also means that your limiting yourself to curves. Artists who think outside the box and use round flowing curves forget why we have a box and consequently stop using hard straight lines. don't limit yourself to water like motions, is all I'm saying.
on a side note, some other reviewers have mentioned color, but I'm not so sure that's important. Casablanca's in black and white and its considered the best film ever made.
all in all, a solid flash, but could use a make-over.
