What can I change about this poster?

I'm still a YouTube beginner (exactly one month since I started learning Photoshop tutorials) so I've only got the most basic of the basics down.

Are there any elements that seem cluttered or misplaced? I'd appreciate thoughts on this design, particularly regarding the readability of the text and whether the color scheme effectively conveys the message. Also, Is the layout visually balanced and engaging? It feels a little off but I can't tell what's wrong.

The message feels pretty obvious, is it? I'm also curious about that.
