If you enumerate tiles from top left to bottom right, tile number 16's left side does not fit anywhere and tile 32 sometimes has weird transitions with pieces with sand on the top and cliff at the bottom. Similar with tile 43 except it has a single vertically mirrored piece that fits on its left side.

Further there are only 3 of 4 tiles which have 3/4 grass and 1/4 cliff, so at least one piece is missing.

And tile "beach2_bl.png" is messed up somehow. Looks like a part of another tile got pasted on top of it.

Tile "beach_lm_04_grass.png" has some dirty pixels on the transparent left half, while "beach_lm_04.png" has not (same with other sand/grass tile variations but easy to see here).

Otherwise these tiles look realy great though, that's why I bothered with pointing out all these things because I really want to use them.

Not working for me :(
