Well you've definately cropped Goku from the bottom ref, to the left image, you can see the green and blue BG left over.
Also, as far the right pic, you ripped his half his hair, face, and neck.
I'm going to close this, and discuss this with higher ups.

@edit: Alright, after discussing this briefly with other admins/mods, we have decided the fact you admitted you used altered images, makes this a moot point. If you hadn't told the truth, it would have been completely considered ripping. In the future, avoid this kind of thing.
