I changed my mind about my favorite artwork by now and would go with seasonal fellana, the pic is so cuuuuuuuuuuuuuuuuuuuuuuuuuuuuuute and overall a lot prettier in detail/colours than the original.
It´s strange that the seasonal artworks are drawn by the same artists as the original pictures, yet they turn out to be skyrocketting more beautiful than the common ones in some cases like Assasin, Fellana, Lelein and Alraune just to name a few examples.
In direct comparison:
Original is eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeew, some half nacked cracked up lady reading a book in a dark room. Exciting.
