Multi-tiled paintings are
a bit trickier, but not much.
Clone to get the sprites,
this time you have TWO in front, and TWO in back (seems pretty locical
so far )
I use the magic want tool
to select the one on the right, and then paste it in a separate layer
on the left, and then nudge it around 'til they line up.
I make the picture now the same as I did for the one tile picture. When I am done I select the right-hand layer and CUT it out. (this will leave the left-side sprite just as it should. Then paste the cut-out section into the right-side sprite, making sure you line it up EXACTLY over the original. If you are wrong by one pixel, you will get an ugly line down the middle!
