watermarks are a little big and sometimes hide some important parts of the content, for example if you check this pic
https://trainwreckcontent.com/wp-con...429-WA0017.jpg ,the girl eyes, cheeks and lips are totally hidden by the watermark, I think no one will be interested on this picture since he can not see the whole face clearly. try to use small and transparent watermarks, or at least if you do not want to use transparent watermarks make sure the watermark does not hide any important part of the content (see the watermark used by shutterstock as an example) .
