Cartoon Style Artwork - Flash & Wonder Woman

I have began doing some artwork in a cartoony style that I am trying to learn and perfect. In an effort to step up my art game, I'm doing different styles in an effort to create a personal art arsenal of skills that I can bring up whenever necessary. This style was inspired by some of my favorite artists. Bill Presing, and Shane Glines. Also the inking work of Marcio Takara is very inspirational as well, and has prodded me to take on learning the brush inking style. Here are two art pieces I did of two heroes from the DC universe. I plan on doing more, and more big pieces. These right now are miniature greeting cards that are fun to do. Let me know what you guys think.
