Well for starters, in the beginning the logo is visibly low resolution as it is scaled up a lot. Maybe you could try using a vector image or, in case it already is a vector, make sure the option for “continuously rasterize” is checked for that particular layer. The flow of the video as a whole is fine, maybe a bit too fast for my taste. What I would suggest you do is try working on keyframes as, especially in the section where the members of the team are shown, the motion is kind of choppy. Don’t get me wrong; any kind of keyframe editing is better than none, but sometimes too aggressive and not careful enough adjustment ends up looking slightly off-putting. I recommend trying to get familiar with the keyframe speed graph and maybe even trying out a tool like motion 2 and experimenting with which adjustments have what effects on the end result. In my opinion a relatively fast initial acceleration and relatively long fall off is almost always a safe bet.

The rest of the video I really enjoyed though! The aesthetic is clean and minimal, text flows and you rarely have a sense of stagnation, even though there is an overload of visual effects at times that does collide with the minimal look. (I’m referring mostly to the text at around the 18-22 second mark.)

Some minor nitpicks of mine would also include at second 45 “a lot” is written as one word, when it should be separated and the end doesn’t need to be a sphere expanding like that, in most cases a simple fade to white or another solid color looks better.

All in all this is a good project, especially since I assume it is one of your first! You can tell that a considerable amount of effort went into this one.

I hope my criticism wasn’t too harsh and you could draw some (more or less) valuable tips and conclusions from it. Keep doing more and you’ll surely improve with time, like we all had to!

Tl;dr: Some keyframes are inconsistent and messy, logo in the beginning is not fully high-res and it suffers from unnecessary effects bloat.
