I think a few tweaks would make the rounded red logo look really good.
I was thinking that the border should be a little thicker around the outside so it looks more consistent. The white background of the youtube logo should be removed. This suggestion is more preference, but I also think the font would look a little cooler as a white.
I am by no means an expert with illustrator, but I drafted up a vector version of your sticker if you would like to see me suggestions.
