I like the energy in your drawings! Like others say, it has potential, and for me, that's because it looks like you're still experimenting with different techniques/styles. Keep going til you get the right flavor!
Still, it you're planning on starting a comic, don't wait until your art is "good" or "perfect". As someone who's been drawing for a while, I can tell you your art will keep changing as you draw your story. Comics are a great way to improve your art skills!
