Wampa Kitten

Original Images
The original images include a snowy mountain background selected to elicit a Hoth-like atmosphere, a kitten on its hind legs ready to pounce, Luke Skywalker on a Taun-Taun from Star Wars The Empire Strikes Back, and a second mountain snow scene from which we extract a foreground snow hill to cover the missing feet of Lukes Taun-Taun.

Mask(s) made with iScissor.
iScissor was used to mask off the kitten, Luke and his Taun-Taun, and the foreground snow hill for compositing.

Final Image.

To arrive at my final image I did the following steps in Gimp:

Load the background image

Load the Kitten as a layer and mask it off using the instructions provided for Gimp

Flatten the image

Load Luke Skywalker as a layer and mask it off the same way we handled the kitten

Do some appropriate scaling and positioning of Luke Skywalker to make it appear that the kitten is attacking

Load the forground snow image and mask off the hill

Again, some scaling and positioning was done

Finally the image was flattened and saved as a JPG image
