This is truely quite a unique style and that's not a bad thing, it just needs a few new points to its design.
I can instantly identify the extreme shading (that must be quite the light source!), especially judging by the most recent Mario. It uses a bold outline of black shades a few pixels thick giving it a cartoonish feel and has high levels on contrast shading. However, some of the shading used are not quite consistent with the current angle of light, (like the hat) aka pillow shading. According to the shades of the overalls, the light comes from the upper left corner, so the entire image would be shaded similarly to the overalls. Those overalls are really shiney too, shading could also be applied in revelence to the material (in this case, denim overalls), some materials require much less shading (like the skin tone) compared to glass objects or other shinier objects.
Not mine. Light source comes from upper right corner, so lighter parts come from the upper right, while darker parts are to the lower left.
Mario looks kind of smug with that look in his eye and the position of his stache'. The top of his nose seems to have a black outline, and also seems too small of a nose for Mario. Try blending the top of the nose with the skin and increase the size of the nose a little. The moustache could also be increase in vertical depth as the face appears to have too much space between the moustache and the chin/cheek.
Other then a few design edits, its quite a style.
