Derped up the source URL for that Asuka/Rei morph, it's the following:https://www.deviantart.com/mcblock2/art/Morph-Asuka-Rei-Conjoined-Sept-2019-814874217
And amusingly, that that Rin Tohsaka morph in post >>20193
is actually by the very same morpher - they just hadn't posted to their DA yet.
Don't suppose anyone has a source for these two works? (presumably different artists)
These were the only two that I didn't recognize and/or was not able to source via SauceNao, IQDB, TinEye, and/or Google.
I did a bit of digging regarding GIN, and it looks like they're not really back per-se but are just drawing art again. What they seem to be doing is simply uploading new works to the same Google Drive that contained all of their works from before they had "quit".
And so that I'm contributing something new, here's art from an artist I don't think has had any of their work posted yet.
(attached image was resaved from JPEG to PNG and recompressed/optimized to OCD levels because the file size was smaller that way)
