What tutorials would you like to see in the photomanipulation guide?

Ok, excuse me if i don't explain this well, i'm not sure if this technique has a name. But i would love to know more about how to make all the images come together and look cohesive in the end. As in... do you mess around with the hue/saturation of each layer? Is it just a light filter put over everything? Yours always look have such a beautiful cohesiveness! That has been a stumbling block for me, once i have everything cut out making it look like they all belong in the same picture and not like... cutouts. Mostly from a lighting/atmosphere angle though, more than just smoothly cutting horses out the original pictures

And thank you so much for taking on a project like making a guide!!
