You can either minimize Tom and click on Quark or just click on Quark. One gets Tom out of the way and the other method just places it in the background.
03a. - Click on Edit>Paste>Paste As New Layer. Now go over to the section with the Layer. Notice the two items there? Background and Raster 1? The Background is Quark and Raster 1 is Tom's partial face. Click in the middle of the gray bar next to Raster 1. Make between 50 and 80. This turns Tom's face transparent. You want it transparent enough to see Tom and Quark. ALTERNATE METHOD NOTE: You don't have to resize Tom's face first. You can do the outline, copy it over, set the transparency so you can see both images and adjust the size of Tom;s face to fit onto Quarks. The best way to do this is make sure you are working with Tom (Click on the word Raster 1 in the Layer section) hold down the CTRL key and tap once on the S key. The resize dialog box appears. Type in a value. If the value does work hold down the ALT k and tap once the Backspace key - this is the Undo, and do another CTRL-S. Keep doing this until Tom's eyes and Quark's eyes match up as close as possible. Thanks to Andreas for the alternate method.
03b. - Move the cursor over and click on the cross. Move the cross over to Tom and hold the left mouse button down. Move Tom's face, by moving the mouse, until the eyes and mouth matches.
03c. - Now go over to the Tool box section and select the pencil with the eraser. Erase the portion you don't want. Experiment. If you don't like what you did Undo (Edit>Undo or hold the ALT button down andtap once on the Backspace key). The more you want it to look like Tom the more of his face you keep.
03d. - Time to color the face. Now, I've already experimented with this. In this image Quark is rather Orange. We want to match only the cheeks, lips and chin to the rest of Quark's face. The eyes may stay the way they are. Take the Lasso tool and draw a circle around the area you want to change. Then click on Adjust>Hue and Saturation>Colorize and make adjustments to Hue and Saturation. See how to make an Orion for a detailed explanation on using this feature. I've already "discovered" a good combination. 18 Hue and 172 Saturation. Also, set the transparency to 72.
03e. - Now merge the layers together. Layers>Merge>Merge All(Flatten).
03f. - You can either use the Smudge tool. Click on the down arrow next to the item above the Erasure tool. Select the Hand with the pointing finger. If you move the cursor over an area, hold the left mouse button down, and move the mouse then you would literally smudge that area with the adjacent area. Or in my case, you can use the Clone tool. You can clone one area and use it to draw a separate distant area. I cloned the area just to the right on the left eye and used it to color the left cheek all the way down to the lips. To use the Clone tool click on the item, in the Toolbox area, that looks like two little people facing each other. You'll see a new cursor. It have a small circle with an ink brush and a dipping bottle next to it. Move the circle over to an area and click on the right mouse button. Then move the cursor to a different location. Hold the left mouse button down. Notice the little crosshairs appear in the area you had right clicked on? Slowly move the cursor around. Wherever the crosshair moves over will be what the cursor draws. See the usefulness? Undo what you did if you are not happy with the results. We have two things left to do.
