Nothing. Just see what's the difference. If you want to know, see Notes and Credits. Also, look into his eyes in the "You" section. He's winking! :-D
How would I draw Felipebross? Let me show you. I'm not bragging, but the difference is that my Felipebross has a better hat, looks a bit happier than the first one, and his body is an oval instead of a "rectangle" and has its arms in view, so are its "hands" (the black shaded-in ovals) doing its put-your-hands-in-your-hips style. Also, he's winking! Watch. ;-) I, myself, drew my Felipebross in shapes. If you're thinking that I'm cheating, then I'm not. This includes circles for his hat, his eyes, and his head, lines for his arms, and ovals for his "hands". The rest, I drew, which includes the smile, and his body. Hope you like it! Credit to all! :-D
