First batch is for the covers of the current novel publisher Red Dog Publishing, then the second batch is for the covers for the physical print of the novel. Image descriptions are a bit long, so I’m putting them under the pictures.
First batch:
[ID: A blond-haired young man (Beak Ran) with fox ears and warm-brown eyes, wearing blue hanbok and holding a golden staff, which I assume is a very fancy looking type of khakkhara (or perhaps it’s very very strange spear), and have a small black swirl mark under his left eye. He is surrounded by unfolded scroll and branches of plum blossom. End ID.]
Used for about 100 first chapters.
[ID: A black-hired young man (Yu Dan) in a student uniform, with one red eye (left), holding a red and blue lamp in one hand and a long twisted dark horn in the other. He has a whitish color scarf tightly wrapped around his neck. Beside him is a small fox and he is surrounded by the branches of a tree with red leaves and red flowers (peony? camellia? I’m really not sure), and an unfolded scroll. End ID.]
Used for chapter after 100.
[ID: Two young men, Yu Dan and Baek Ran. Yu Dan has casual clothes, he is sitting and holding a paper sheet and a small stick (??), looking of the side. Baek Ran is standing beside him, in green hanbok, holding an unfolded scroll and looking at the viewer with a smirk (his eyes are golden yellow here). They’re surrounded by a tree with red leaves, pale-pink flowers (I don’t even attempt to recognize), cotton shrubs and water. And around them play little squirrels in blue coats (one sits on Baek Ran arm). End ID.]
Used for side stories.
[ID: Yu Dan and Baek Ran again, laying head up in the water (Or maybe the background is just blue). Yu Dan wears a red, blue, black hanbok and looks much younger than on the previous covers, looks in Baek Ran direction, who is above him. Baek Ran is upside down, wearing a white-blue hanbok. He looks at the viewer with a smirk. Some kind of white symbol in the background behind them. Three koi fish swimming around them.End ID.]
Current. Used for the special stories/side stories 2.
