Oh wow, thank you for the compliments! I am actually sorta working on a "sequel" already, with more focus on Kel because he's fun to write.
Buuut I do have to point out that I can't take much credit for the character art! I'm glad I apparently managed to make it look "natural," through editing of colours, character sizes, giving Kel stubble, adding the cigarettes to hands, etc., but as the About section and credits point out, the actual art is by Iwose! Who is a very good artist and allows his Picrews to be used for more or less anything. So I can only in the vaguest terms maybe take some credit for some of the designs. I encourage you to play around with his Picrews, though, there's a lot of fun stuff there I didn't have a chance to use.
