Just out of curiosity, that's not a Porsche, right? I do love that little guy. Looks awesome for the image. I like the thumbnail itself, the letters are clear and stand out well. Personally, I would suggest a border, maybe white, not too thick, not too thin. Makes it stand out a bit more. I have a red outer border and a white inner border because the white border looks nice on thumbnails and makes it stand out but it blended in with the white YT layout unless you had dark mode on. So I added the red border and now it looks better. Of course, that's just me. You could add a red border to match the letters or a bluish one to match the character in this thumbnail.
