Well, finally done what should have been done ages ago. It took someone to spend time and get this translated into English after the RAWs were released 4 year ago. Raws weren't great, but my group spend the time to make it look good. Also, what's up with Takemasaya's works being seldomly done. Well, my group's on the case, though it'll be a while til I can work on the next Takemasaya CG doujin.

Thanks for translating this. You did mention that the raws weren't great. Here's one reason why. Since every page here is downscaled to 1280x, I assume you probably downloaded the resample version of the raw instead of the original full resolution version. Resamples are always downscaled to 1280x resolution, while the raw was around 2050x. You should use the full resolution in your next projects. There's usually a big difference in quality between the original and the resample version created by EH.
Here's how you can download the galleries in their original resolution:
Click on "Archive Download" and then "Download Original Archive". If you prefer to download one page at a time, make sure you download using the "Download Original Source" link below each opened image in gallery. If you download via torrent, then choose the torrent with bigger file size. Don't download the file with 1280x in its name.
