This is hilarious! I'd never portray Lavos like that in my thoughts, but this is just... awesome. The expressions just add even more hilarity to the picture.
I think you've done the clothes well, maybe Magus' look a bit "today" like, but that's just a minor mistake. After all, you worked on the picture from memory! And the colors also look great. Shiny!
I'll be adding this picture to my favorites! (And, I was actually listening to World Revolution when I checked this picture out...
)
