A fire digimon

The second time I was about to draw something for DA, I've decided to have my most beloved little buddy Pyro as a theme. I actually wasn't planning to upload a traditional drawing of him on here, but to to make a line art, import it to Photoshop and then make a digital picture of my most respectable and loyal partner ever, and with that I mean my little brother. Yes my little brother is my real life Pyro, from whom I originally figured out, Pyro's unique bad ass, and spoiled little brat's character So as I was inking this he saw me doing it, and really jumped here and there due to his enthusiasm telling only one thing: May I paint this, may I paint this? He wanted to paint this with his crayons from school. By seeing this you can understand if I let him to do it or not, except from the gradient feature on Pyro's tail's flame and the shading that I did them myself.

So, I'd like your opinions everyone about how does this looks and what improvements you think it might need to reach perfection. Of course if you are a pro drawer or cartoonist your opinion counts more, but everyone is welcome to tell me what he/she thinks about it. No rude comments please
