Not awesome to let those greasos have their way with you. I think.

Thanks for the release, but for your future ones please do use the original size images, not the downsampled-for-viewing ones you see in the galleries (or download from NH***, or save from Tachiyomi). Otherwise, apart from the smaller size, you're starting with a noticeable drop in quality right off the bat (gallery images are saved at 80% quality, usually you can spot JPEG artifacts by zooming in on diagonal lines).
Ways to get the originals:
1) Torrents (if still seeded, usually that's the case for stuff released in the past few months; just avoid those with 1280x in the name as they're or the downsampled version too)
2) Archive Download link (choose "Original Archive", may cost some GP depending on lyour level, stars, how old is the gallery etc.)
3) Page by page, using the link under each image that reads "Download original source" (if present, otherwise that gallery image is already the original).

This series is so extense that I think a tutorial is needed to follow the proper chapters.
