The first two have small manipulations like using the lasso tool and the magic eraser, they are is a middle stage that is still fun and they do not look too out of the ordinary. The last two I would consider finished they look like post cards to me and I really like the contrast changes in both. Then I used some magic wand and color gradient. Their is some mirroring going on in the last two as well as some negitive space that adds to the contrast in the positive space.
