What do you think about my thumbnails?

Overall looks too dark and hard to read. Also there is too much information with the logos on the image. you should focus on what is your subject and use a readable font like Bebas Neue or similar (avoid serif fonts).

Honestly, it does not look good. You need some more time behind PS

thumbnails about hacking xD i love it, but its looks nice

I think it looks really sick mate. But I don't really know if I would Klick on it when I see it under recommended videos. It needs something special that no one else has.

This is really busy and doesn't have a good focal point for the viewer to notice as they are scrolling through.

C'mon make you can make it way better than that quit trying to copy other thumbnails its so typical

Honestly, it needs more work, make it unique; it looks like a typical clickbaity youtube gaming thumbnail
