Though I never read Marvel comics, I sort of know who this guy is, though Marvel isn't for me, I still watched Spiderman and Batman quite often. A very interesting piece of work, the lighting effect and the dark of the night is inquisitive to say the least, this is a good example of drawing out the light from the darkness and goes well with the theme. I wish you luck and I do hope you win!
I know how that feels, but hey you made an awesome piece of art that plenty of people will see! also yours looks very professional ^u^ un like mine which I could only do in color pencils but I'm proud to call it mine
