nah. not really... here's the idea; make a new canvas with grey color because grey always does the best acting as base. and then you place the picture of...let say for example yuto, then change the yuto pic to color burn. then you can play around with the color balance and brightness/contrast. sometimes it's also good to duplicate the yuto pic layer and use another mode, maybe soft light,etc.. just try experimenting around.
^^ glad to be able to help =) another tips is to use icon texture just find them on graphic sites or deviantart, overlay the texture on the icon, change the mode and voila~ haha..
Hurm, I did change the mode but maybe I should adjust the brightness??
