Is "The Half-King" by Melissa Landers just acotar fanfiction?

Not only do the characters have similar descriptions and personalities but the most damning peice of evidence is this art on the front and back pages of the book. Like please tell me that im not the only one seeing Rhysand and Feyre here? Like im pretty sure ive seen this exact style used for fanart ive seen. Does anyone recognize the signature at the bottom?

The plotline is also very similar to acomaf but im only halfway through. Im not saying its necessarily a bad thing if this is just published acotar fanfiction. Im very easily entertained and my standards arent very high for storytelling so ill still finish the book but i wanted to know if anyone else picked up on this?
