Alright so I'm going to go down the list i use and explain my rating.
I really like the mix of black and white along with color. Everything seems to be bordered nicely and makes the scene pop out more.
Doesn't seem blurry in game and the lines are crips along with the subjects shading.
Obviously you did not create this piece of work as it's from the JoJo's Bizarre Adventure manga. I haven't seen many sprays of this on the site so it goes up to a 6 on originality for this site. Also you might want to take this out of the GBX program as It's not original work and will eventually, at least hopefully, be ignored altogether for program eligibility.
You've managed to pull everything together in a nice format and I love the contrast of black and white drawing to the colors as well as the added depth dimension form the addition of a border.
Overall rating= 8/10
