Okay, this does remind me of the 90s. Very good use of fads that were current then in your drawing here, such as the plaid and baggy clothing, ripped jeans, the glasses, the look of uncaring to be "COOL". I think your coloring is also very good here and uses a good light and shadow source. I wish the background was more than gradients and the color pink, but it does work for this 90 theme.

Give us a background here, maybe some TMNT or Simpsons
