It always seemed to me that the pyrokinesis should be more than just throwing fireballs--I can't wait to see some sort of movie treatment where Mario's got fire everywhere and is torching the place, and Bowser's just "Um...oh..."
This is the absolute coolest picture of Mario i have ever seen. You made him look as powerful as his character is. It reminds me of a Mario/Vegeta hybrid, and mario's natural confidence comes out in this very well. Good job!
