I think its okay to draw just because, and let your imagination run wild.
Try drawing the same character more than once, don't let it all be 100 different characters, what is he doing? what enviroment? all your characters have a feeling of being humanoid type, two arms legs a head and a body, are you really just trying to draw people? do you need to refine what composes the structure of how they move, so that the body tells you the flow of which it is going.
