Don't be so harsh.
That was fantastic. I liked the plot. It had a creative, but unoriginal twist. I, as well as everyone else who watched this, thought it was suicide. But chainsaw? Wow. Definitely changed the mood of the flash.
You're animation skills are par. You're art is great. Work on this big projects. Spend lots of time on them. By the time you finish them, you will have learned a lot and be able to touch them up.
Infact, this flash was almost perfect. I feel as though the ending was rushed, but with a bit of touching up - it'd be fantastic.
I did not, however, like the text for speech. Voice acting is the way to go, in my opinion. Unless you feel as though it'll ruin the "sad" mood, in which case the text shouldve been displayed on frame, instead of a white box. I assume this was done, because you rushed the ending.
I also liked the music you had playing. It fit the story very well, but sound effects are a requirement. A chainsaw noise would've helped the drastic mood change, and pumped up the audience.
All in all, don't be so hard on yourself. Shit was dope. Don't rush, and you'll be submitting front pages in no time.
