I think it's a bit too low resolution, you have to think about how small thumbnails can get on YouTube, especially on the mobile versions. I understand that this is probably an old game but you should try to find a higher resolution image for it. I also feel like the game cover in the corner is too small to be needed in the image. Consider making it bigger or just removing it. Looks good so far
