- Thumb #1 can be brightened up a little bit.
- Thumb #2... If you add a little contrast, her hair and eyes will pop out more.
- Thumb #3... A little less bright, a 2-3+ contrast and if you really wanted to put the time in, you could edit the color balance a bit. Could also be centered, better as well, but that is variable on the screencap size you were given.
- Thumb #4... 3-3+ contrast again would bring the red of the tongue out, the white of the cum and her hair.. Could also use some centering.

Above all, I'm not much of a fan of the WM player icon on thumbs. A lot of people use it, but surfers that surf MGP's know that clicking a thumb will lead to a movie.
