These are the two original screenshots combined to make this picture: http://www.furaffinity.net/full/6856889/

Changes I made include the following:
1) Superimposing the lion’s head on the wolf’s head. This was necessary because lion Barbarians (as portrayed in Perfect World International) have smooth furless bodies... and Yo has a thick lion pelt! I had to use a wolf Barb’s body to be accurate. Also superimposed the lion's fingers on the wolf's, for better detail.
2) Adjusting the Colour Hue of the lion mane to make it brown instead of bright red.
3) Adjusting the Colour Hue of the wolf fur to make it tawny instead of blue-grey.
4) Adding the “eyepatch” on Yo’s right eye.
5) Adding lens flare. I know, I know – this is the most abused function of graphics software, but appropriate in this case, since it mimics the lighting in game arenas!
