Complete set of transition tiles reference

This week I've been trying to narrow down all the transition tiles that I'll have to create for my game, after some research I found out that most games do not have diagonal transitions, so I went ahead and created my own transitions from scratch, this is what I got(tiles are 128x128):

(The reason for the 4 full tiles is that I have 4 variations of them and use them randomly to lessen the repetition effect).


And here a sample tilemap utilizing it:


Finnaly, the same tilemap utilizing real tiles, a modified version of the adventurer's pack grass and dirt:


These transition tiles allow for horizontal, vertical and diagonal transitions as well as transitions from several different tile types in a single tile without overlapping.

The reason I'm posting this is twofold:
- I need some people to review it to see if I'm missing any necessary transitions.
- As a reference for anyone that needs to create transition tiles.
