Here is a Halloweenie Video for you!
Step 2: Face Parts
Once you have the parts outlined, just hit CONTROL+C, CONTROL+V and then you've copied your selection.
Next, hit the letter V on your keyboard to activate the "move" tool. Drag your eyes and mouth over to the image of the orange and you're mostly done! :)
Step 3: Erasing
Zoom in A LOT, using CONTROL + ] , control and the square brackets are shortcuts to zoom in and out. To center your image and zoom out, press CONTOL + 0.
Once you're zoomed in, select the eraser tool and above, on the top tool bar, select the fuzzy circle, which will erase things with a soft edge. You can see the settings I used if you want to duplicate the same look. Just don't use a TINY circle, or a BIG one. To get the size you prefer, have the fuzzy circle selected, click somewhere on the image to make the options box go away and then hit those [ and ] brackets to change the size easily. :)
Just slowly and easily erase the excess around your eyes and mouth, leaving a tiny edge. You want your eyelids intact and some edge outside your lips. (More edge than I left.) :)
