you really need to work on your image a bit, try top make the blending between images a little softer otherwise the edges are just too distracting. Try to fill the entire left hand side (screen left) of her face with the skull, otherwise it just look a little strange, and if that's the way that you want it then maybe try adding a shadow. Simply cutting out the skull and pasting it on someone's face is too simple in my opinion, but good luck.

great idea, but I agree with ponti, you might want to go back and work a bit more on the blending.

u have to work it a bit more , it looks like scull is not from the model u have to shape it to the head, but good idea

Maybe try a soft edged eraser on low opacity, that might blend it all a little better..

who? HAHAHAHA!!! sorry but i think the title is really funny for some reason. XD

who cut the skull that bad and forgot it on the picture of the girl?

mmm, sorry but I don't know what to say

i forgot to thank pepo for the use of the girl. thanks pepo
