UPDATE: 11/14/2018: Pink Lady Mage how now posted this version as a free preview on their Tumblr. https://pinkladymage.tumblr.com/post/180111610889/cordelia-from-fire-emblem-its-already-so-cold. We're all good on this image.
Although it appears that the site you found it on was itself in error, unfortunately. Thus, your sourcing is incorrect in turn.
pinkladymage.tumblr.com is indeed the artist's Tumblr, but she has not posted this piece there.
Instead, its a Patreon/Gumroad piece. PinkLadyMage has it on sale here alongside various variants: https://gumroad.com/pinkladymage#
Unfortunately, once it came to the moderator's attention that it was ACTUALLY premium paid content from the artist's Patreon/Gumroad, we were forced to remove it from the discord.
Which is really unfortunate and regrettable, because they were amazing pieces, but it was important to correct our error and respect the artist once the error was realized (the originally posting mod didn't know it was premium content, having been sent the image by an acquaintance without this detail mentioned to them).
It is available on the artist's Gumroad though: https://gumroad.com/pinkladymage#
Probably not the answer you want to hear though. Sorry. :(

Apologies for the drama tonight. Sometimes being a moderator is no fun. We're now also discussing making an update to the rules to clarify the official stance of the moderators regarding paywalled art.
Part of the confusion of today was the result of a mess-up on our own part as the moderation team, not realizing at first that a piece posted on the Discord was actually from a paywalled set. Our great apologies for inciting this drama with our error in the process.
In the meantime, here is a publicly and freely preview image of a great new set of art by PinkLadyMage that will certainly remain consistent with any rule updates that may or may not happen, regardless of the outcome.
If you're interested in the full set, I've happened to buy it myself, so I can describe its contents:
(It takes the form of a series of sequential work-in progress steps from the beginning to the final image, then variants thereof)
WORK IN PROGRESS IMAGES
1.). Line Sketch of Cordelia, clothed.
2.) Line Sketch of Cordelia, nude.
3.) Basic shading of Cordelia, nude.
4.). Now also with the background, basic
5.) Further advanced shading
6.) Addition of bikini
7.) Further enhancements to the shading
8.) Lighting effects added
9.) More light added, also, nude version
FINAL VERSIONS (permutes combinations of having bikini top, bottom, and gloves - 8 combinations):
The same pack also has similar arrays of artwork for an image of the artist's cute OC/Avatar, PinkLadyMage, and Bowsette/Booette, for reference, included in the overall package.
