How to use it seamlessly

Maybe this isn't the right way to do it, or maybe it is but some of you don't know it

This project its made to work seamlessly, to do it, you have to use:

(connecting tiles to give it more length on x axis) 

- two pixels from the left tile, and one pixel from the right tile

(connecting tiles to give it more length on y axis) 

-two pixels from the top right tile, and one from the left bottom tile

(connecting tiles to give more length on x, y axis) 

-ten pixels from the combined top left and top right tile, and 15 from the bottom tile 

The same idea works with foliage, keep in mind to have in mind where the pixels are when a tree trunk is in the way, to help you out, every tile is made of 2 pixel long on the corners, the rest of them are 3 pixel long
