More dynamism!
Crisp and clean are two very good and applicable descriptors for this work. Unfortunately, dynamic is not one. Cut to different visuals more quickly, don't give the viewer time to get bored with what they're seeing. Most of the stuff in the beginning could have its screen time cut in half to vastly improve the whole of the work. Viewers get the idea of what you're trying to convey pretty quickly; we don't need to see the robot arms going through a second repetition, or a second gleam of light going across Dude's goggles (which may or may not do nothing).
Study, ironically, some of the better Animutations; those by Andrew Kepple and Neil Cicierega are some of the best, and getting familiar with the way their works are timed, scenewise, will help your own timing as well.
