This is more-or-less what I envisioned the world of Super Mario Bros. as being like (well, except for the Koopa Paratroopas being sea-turtles) back when I first played the first game. I was a little bit disappointed by the cartoony style of SMB 2 & 3, and even more disappointed as the series just got more and more cartoony over the years. It's nice to see some art of the exotic and dangerous alien world of the Mushroom Kingdom I fell in love with as a kid.
