First I cut off washingtons face and created a new image. I then cut my face out and pasted it in the same image. I used the patch tool to patch out the eye sockets, knose and mouth. I then duplicated the layer twice. I set one to blen with a soft light and the other to blend by multiplying. I messed with the opacity on both layers to get the textures right. I went to my face layer and desaturated it. Added a hue saturation layer and messed with the color a little. I then pasted that composite image back into the original mount rushmore. I used the erase with an opacity of 50 and blended the edges in. Adjusted the color a little and bam!!! Done. The color still isn't perfect but I didn't spend to much time on it so...
