So before I get to some of the cooler tuts today, I wanted to upload the rest of the characters from the new Cartoon Network show 'GrojBand'. Having said that, here is “how to draw Mina Beff”, step by step. So from what I understand Mina is Trina's best friend and Trina is Corey's sister. Mina purposely had her birth name changed so both her and Trina would have rhyming names. Drawing Mina should be as simple as the other characters from GrojBand, so keep your pencils at hand and continue to look for more drawing fun.
