You still don't seemt o understand that you cannot change the borders...
Only what you draw within the 128*128 square will show, you aren't allowed to edit the borders to blend into your pic, you have to edit your pic to blend into the borders, I suggest you make a layer that contains just the borders and keep it at the very top of your document so that you can draw underneath it but it shows on top and you can see how well it will blend in the end.

You pictures are of an interesting style, not bad. But you just don't seem to understand how to blend properly.
