Here's my third 23 in '13 Challenge piece inspired by John Anealio's instrumental song "7 Rounds" (available for free download on his site). It took me longer to finish this piece than the previous two for various boring reasons which I will spare you. I was debating making the background all vector art, but once I started playing with the plain inked version, the imperfections grew on me.
I spent a lot of time playing around with the colors for this piece. I'm still not sure I'm 100% happy with the results, but I do see improvements in my coloring techniques... so huzzah, I guess.
