Incidentally, what program did you draw it on?
Hope you don’t mind a slight bit of nitpicking: Only Strut should have yellow eyes; Ozzy’s eyes are orange. Strut’s underside also isn’t that dark, although the color of his back compared to Ozzy’s is fairly accurate.
I have noticed a few color errors. However, I'm not willing to fix a few errors in fan art. I will only draw fan art if I have any funny ideas for certain characters and if I have time to draw it. My main focus is my own comic and my own characters.
Nothing wrong with that. Just to let you know, I never expect artists to edit the errors I point out when I review fanart; my intention is mainly to provide notes for future reference, like if the artist decided to draw a particular character again. As always, if my nitpicking is more annoying than helpful to you (since you don't draw LBT fanart that often), I can simply exclude it.
