It happened to all the iso-collabs before. First half of the tiles are ready in a week, and then it's half a year of long and slow finish.
This one is actually moving a lot faster than the previous.
Thanks Finlal, I'll do that! 
I'm just trying to attract people to join this project. Somehow it all slowed down with collab, maybe they need some boost...
Cool tiles. Love your input in the collab.
But I think dividing them in the final image would be more readable.
Some really fine work here.
