I think you were absent during the POOR JODO days. It was one of the recurring jokes here, in response to the flood of POOR JODO threads that were created. Some members wrote long, trite sigs, along with banners that displayed their lament and true, unfiltered love for him, and what a FAG griff is for what he did to him!! 
Sounds entrancing.
Well, he has fiery red hair too, and his jaw is too sharp to be Grunberd's (at least to me)... If you have any suggestion, feel free to voice it. 
Sure, this probably influenced by the visual image I had in my head for the longest time, but I always pictured Isidro to be blond, I realize thats not the official color.
(borrowing from the Encyclopedia, hope you don't mind) As far as the sharpness of the jaw, I would say Grunbeld has more chiseled (sp) features, while Isidro, while not entirely round either, is more child-like in size and shape. I guess the more obvious reason I said Grunbeld before is the fiery red hair. While Isidro has spiky hair as well, Grunbeld's looks like its on fire.
That said, I might as well add in that I no idea how I'd go about representing that change in a 20 by 20 pixel format. So take whatever critique I might have with that in mind.
But still, great work guys.
