I can get a giggle out of it, and I'm not ashamed to admit it. Okay, believability could be considered an issue, but silly sounds that made kind of a joke of the sight didn't distract from what you were doing with the screen. You also seem to have listened to it, yourself, so it's not too ridiculous, or earsplittingly annoying. You also didn't go silent, taking on some of the audio responsibility to create something genuinely decent on your own. These are all good choices in a first animation, because too much too quick can overwhelm you. You didn't apply a music track, but that can also be an unsure bet with some viewers, so you're focusing on your animation quality. You kept this minimal approach, avoiding messy and distracting effects that might not sync' up well in playback and stuck to what you know. You've set up the buttons from the start to give a viewer choice of where to begin his view, and assumably, most would start from 1 on their first view, but many will choose 2 (and a few will only seek 3) after that.ДЄudio is what it is, and good audio can make you, while bad audio can break you. This is a good beginning 'archetype' or 'template' to work with. Over all, (especially as a first ever animation) Good work! Seriously, you've thought of most of the bases and covered them. First animation at all? Or is this the first one you ever cranked out in just a few days (as opposed to weeks or months)? It's at least kind of impressive either way.
