I've been working on 32x & 64x resolution textures for my 16x texture pack "Crisp" (formerly "Chunky Bits"), which can be found here.
Once the 16x version is complete, I plan to also release the pack in higher resolutions. Since this is my first time working in resolutions higher than 16x, I wanted to post them here first, so I can get some feedback. I completed some of the more commonly found blocks first (Cobblestone, Stone, and Grass), just as an experiment. Let me know what you think!
The cobblestone doesn't look very good in 64x and the stone has a noticeable seam-type thing on 64x.
The dirt/grass looks nice though!
Thanks for the feedback! I agree that the stone in 64x tiles a bit strange, I need to fix that up a bit, but what is it that you dislike about the 64x cobblestone? I actually don't think that it looks too bad.
