Once the word that my first round opponent's character of choice was Raphael of the Teenage Mutant Ninja Turtles, visions of Thor drinking turtle soup from a half-shell in a great hall of Asgard sprang to mind. And then I realized it would be kind of tough to draw this fight in a way that would come off as believable. And then I thought of Thor as a frog battling Raphael and decided to pass as my choice was full grown Thor as a god.
And so, I began to doodle out ideas for the battle ahead on Sketchbook Express. I ended up liking the depiction of Thor bringing down Mjolnir on Raphael on the Bifrost to the left.

And I then copied it and created a whole piece with it, filling in black areas of space, drawing in a layout for the bridge and Asgard in the background. I then printed this off for use in 4D...

Taking the print off of the computer drawing, I light boxed it and, using a blue line pencil lightly drew in the layout for my final piece. I then inked it using Faber Castle Pitt Pens, brush pens and manga pens for the gray tones...

Finally, I scanned it back into the computer and into Photoshop where I enhanced the black areas, expanded the starry night and added in Raphael's caption.
