New wip!...And spot the mistake! (Patreon)

Hi guys! :)

A new WIP has been posted in the folder and...I've just realized I made a huge mistake on the drawing! ^^" By "huge" I don't mean "difficult to fix", oh no, that will be a super easy fix. By "huge" I mean "this is totally illogical, I've never made that mistake before, I should go back to art school"...Will you be able to spot it? Feel free to comment below :)
