Okay, I've been playing around with it for a couple hours now. I love what you did with the rivers, and the transitions! One thing I would like to see is larger mountain options, or some sort of "tiered" sections to make mountainous areas look bigger. I'm also not sure what to use for farm land. You had that in V1, but I don't see anything that is obviously a farm area. I could be blind and haven't explored enough though. I also had quite a bit of trouble with the roads not lining up with the grid, so I ended up just placing them freehand, rotating and flipping as needed. This I didn't mind, but I'm not sure how I was supposed to make a continuous path otherwise.
Overall, the options in this pack are amazing! There are so many variants and positions to fit every transition combination. Not only that, but I love the options to have a flat shore, semi-rocky shore, and full cliff shore with the summer Fjord! I decided to remake the 150x150 map that I made with the V1 tile pack, but this time I'm making it double the scale.
Another suggestion for things to add: Full forest options and transitions. I've got some thick forests on my map I would like to recreate.
