Feedback on YouTube Thumbnails & Graphic Design

Hey BHW,
I’m a YouTube thumbnail and graphic designer focused on bold, click-worthy visuals with portfolio to back it up... Been experimenting with vibrant colors and punchy text to boost engagement. Anyone have tips on what works for thumbnails or branding graphics? Happy to share insights or brainstorm ideas!

Design clickbait thumbnails, use controversial texts and play around with fonts, with time you will get noticed and you will be able to build a community with engagements
