I really like this texture pack, it gives everything that nice post-apoc look while keeping the look of the default textures!
But, I do have one question at the moment: Why does night look so bright? I'll post screenshots:
Oh wow this texture pack is unbelievable I really recommend you download but that wooden door texture I personally think requires a bit of work it looks... kind of out of place. I know it's supposed to be a wasteland and all that but it seems to stand out and be the odd one out in this texture pack a bit but seriously that's one great texture pack good work!
For my two cents, this pack looks awesome. If you want my advice, though, I'd find somebody else to help you with the pack, because updating a Texture pack on your own gets super annoying after a while, and it'd be a shame for this pack to stop being updated.
Speaking of which, take your time (which you will anyway, I guess). Good luck!
