Ah, it appears I have introduced you to one of the earliest songs ever uploaded to the Audio Portal. While writing a long, constructive review for an animation that's barely half a minute may seem ridiculous, keep in mind that I'm writing this as constructive criticism for any future flash of yours.
First off, the boy and the way he was designed. One of the things that always bugged me in your animations was the eyes and how they're just a bunch of lines. Circles with generic pupils in them would even look better. Some cartoonists can get away with lazy eyes like that, but only because it corresponds to the rest of the character well. The lack of detail you put on his other features merely emphasizes the poor-looking eyes.
I appreciate that you, unlike other animators, devote extra effort to shading your animation. Though the shading is incorrect. The light source you have in mind is very inconsistent, and if you go on deviantART and look up drawings of people, nobody shades the neck like how you did.
Also, when his arm is moving: I saw that it's partly shaded, but when it hits the part of the body where it's inconsistently shaded, it disappears. It's disconcerting to look atttt and just plain awkward.
An actual person's head is not a circle, and although I admittedly do use circles for some of my characters, their other facial features compensate and correspond well to my choice, so it masks that fact and compensates. The nose looks notably odd, as well.
When the guy was walking, I think you messed up with the easing. First things first, before addressing the easing, the boy's arms extend too much. The way he moves is like he slows down and speeds up and randomly. 100% out and 100% in is what I use, but only when he's about to finish walking, not when he's taking a step.
The text falling on the boy, in particular, was great. The actual timing and execution is probably much better than what I would have done. It's the text that's bad. It looks like a traced bitmap. If you're unfamiliar with a traced bitmap, rip off something from Google Images and select 'Trace Bitmap.' It looks very, very ugly and horrid.
My suggestion on how to fix the text would be to take the text you already have, make a new layer, lock the layer of the text and make a clean outline with consistent coloring and the text would actually look very decent.
2.5/5
Please note I'm not saying this to be mean, but only to help.
