4 different images were layered and resized and positioned to where they are suppose to be at first. and top 3 layers were added layer mask. after couple hours of carefull fine tuning the layer mask the smooth transitions were achieved. cloning and healing and patching tools were used to remove and blemishes and burn tool was used to create some artificial shadows. this was a very fun project, hope you guys enjoy it as much as i did creating it..
