Cherio, can't wait.
Edit: Also, since the entry asked, yes, I'd absolutely love the original sizes.
Edit 2: Also, something you might not have considered, or maybe things work differently in the hex mapping program you're basing this on, but at least Tiled supports semi-transparent .png:s. It works extremely well for making various doodads, such as the soft shading for, say, a tree or houses or something. It's great for making caves or tents or towns that you can plop down on any terrain on a higher layer and still have it look proper.
Edit 3: Alright, so, my editing is getting ridiculous here, but one last thing: For all that is good and holy and dear in this world, please, for the love of god, leaf trees with snow, as well as trees in snow without leafs at all. Every tileset I can find have full summer leaf trees, and then it has various pines in snow. That's it. It's impossible to find tilesets for making seasonal things, because apparently, areas are either covered in snow and have pines, or it is summer and they have leaf trees.
I'd also commit various crimes against humanity for spring/autumn sets to match, but now I'm just getting greedy.
