Masking the donkey with the refine and select tool.

Put the donkey head on the tiger, and masked the bottom part of the head a bit to blend it.

Put the wings on.

Put the tiger in a jungle, and masked the bottom of the tiger a little bit too. 

This is the second to final part, because I was trying to make a shadow but I couldn't make it look like how a shadow should be.

This is the final version that I turned in, and I think it looks okay for just blending things together.
