Ayeee whassap. 
So a few tweeks here and there to better exemplify diversity in the character designs. I meant for Undyne to resemble an Eastern Asian and hopefully did that.
Grillby's design I kind of made up while I drew the comic so I'm not sure if I depicted him correctly. If anyone has design suggestions I'm open to hear them.

EDIT: 
Okay, it was Grillby's hair that bothered me so much. I think it looks better now.
I tried having it unkempt and wavy to fit the whole "Fire" headed aesthetic, but it didn't scream "Grillby" To me. I think something sleeker and more refined suits him better and bright red of it does just fine to portray his fire... monster... thing 
Thanks for the idea

EDIT of the EDIT:
Jesus fucking christ I almost left out the dialogue ugh
Someone get me coffee
