Hey! You're definitely on your way to getting great stuff done! These are honestly pretty good, but I think you play with camera movement a little too obviously on some parts. I think you need to play around with cutting angles with beats, so instead of us seeing the camera swing around, the camera would suddenly be fixed on another viewing angle without transition.
Also don't be afraid to add more elements to these! Intros are usually only a few seconds long, but you wanna keep people's attention by having things happen around the point of focus. You did a really good job on this by zooming out quick and momentarily changing the text in the beginning of your Idiotic Gamer intro.
Keep working hard! I can feel you have what it takes to make some really good intros!
