Sketch:

Yet another event that was, sadly, spoiled for me through fanart before the premiere here in the US. Nevertheless, I just had to acknowledge it.
As for the sketch, outside of the usual anatomical fixes, the face, hair and mask all had to be re-mapped digitally thanks to the low quality of my reference. The..... hand that's holing the staff also had to be traced inn (as best I could) thanks to all the black blending together and makin the details difficult to make out. The trim of the gloves was also traced in because I somehow completely missed it when I was drawing as well as the pockets, once again, because of all the black blending together in my printed reference. The details of the Rabbit Miraculous were also traced in for accuracy and a basic pom-pom clipart was used for the end of the tail.
Miraculous: tales of Ladybug and Cat Noir and all of its characters, including Adrien, are (c) Thomas Astruc, Zagtoon, Toei Animation, and any and all other respective owners may have missed/not be aware of. I do not own the character in any way, shape or form, I am just a fan!
