I think graphicriver/envato watermark needs to be improved, it barely shows on some images. Reviewers have rejected files that have my own watermark.
I suggest to give watermark more contrast, some kind of black, gray and white beveled edge or shadows, more thickness.
i.e., can you see watermark on these images?:
wait! I think I spotted a line… ahhh no, nothing You are right – they have to make them more visible, especially in your case!
