1) Is it just me or are the coffins really tiny? They appear to be less than an inch a piece while an average RPG scale character is a bit more than an inch high. Is it a good idea to rescale the whole lot?

2) Are the doors on the church supposed to be cut in some way to be open-able? This is a secondary concern for me since I got this set for the props, but it does make me wonder.

3) Can someone who has both Hinterland and Grove tiles take a picture of them next to each other, I'd like to see how the textures compare before starting to print things out.

Thanks for any responses in advance~...

1. I haven't built the coffin, so i can't say, but they do look a little tiny in the pdf.

2. I don't think the doors were intended to be cut. They should be left as is.

3. Hinterlands has more green than Wildwood, which has more blue in its tint.

You could have a look in the planner, using modelset below (unzip it in the tileset directory of planner)

Yes you can cut the doors to make them openable. But by default they are not marked up to be cut.

It's the same way with most of the older sets.
I almost always cut open the doors unless I really need the wall to be solid.
