My Drawing (generic EXPO & suggestion requests)

[Nieves and Co]

Konnichiwa;
In the attachment that follows, I present one of my first drawings to go into mass-production & vending... However, I feel as though it won't sell for the $20.00 goal ($20 for cuts & 8x10, $20+ for larger sizes + shipping), so I need your help for suggestions and enhancements that I can make to the drawing to make it sell for more.
Doumo arigatou gozaimashita!

Sometimes people can come across as mean.....

are you sure you want to hear negative comments?? Hopefully people replying to this will remember you are young and just starting out as a new artist.

Which is exactly why I need to hear any comment/suggestion that comes, positive and negative just the same, in order to become a better artist.

To me, wheter it is positive or negative is insignificant, as long as it provides some sort of tip or information.

How about some colors? Oh, and a gun-toting babe in a revealing cyber-punk getup in the background would be nice, too.

No colors, disgracefully I suck with colored pencils and/or crayons.

Hahaha, maybe I can do this one soon enough.
