this shows good planning skills but the drawing ability and animation is very poor. Also your display picture is ridiculously bad. I make games professionally and this would never fly. One thing I do like is the idea of this drawing style being a deliberate choice do make a very unique look for a game. Maybe consider re-drawing these assets in digital format.

Any time man. I used to Art Direct games so that was sort of my job. In regards to the display picture above. Id suggest showing a face in the image. People connect with eyes so at the very least show your eyes in the picture. Think of the subtext an image conveys and how you want to brand yourself.
