Ok, so, I completely missed that Curse's quills had a darker shade of his fur at the tip of his quills (thx for RoseCandy for letting me know of this detail), I also took the chance of adjusting Curse's expression and a bit how the face is drawn for both Hex and Curse

As for the Sans drawing I promised before, it's still in progress (actually, it's 2/3 of being finished), I've just haven't gotten the chance to work in much as of late due to University and having to finish a mod thing I'm working on (yes, I'm in a FNF mod at the time of this post, yippie!), so the Sans drawing may take more than planned, so ye, see y'all next time
