I can't imagine many people still come back to these posts after a few days have passed, but for posterity I wanted to make a note of this anyway.
Here's the specific comic, but frustratingly the site distributes it -- for fair bandwidth reasons -- at reduced quality. I wasn't able to figure out how to ask the site to serve the original, so the best quality I could find is from the original artist posting it on reddit here and here. It's a high-res, seemingly uncompressed file so it's probably the original quality.
