Haha! i really like the character, and i think you have a bit of a peculiar style thing going on, i do however, think there are some problems with it.
Let me clarify;
- A bit of abuse of inner black lines; especially around the underwear area.
- Lack of proper antialiasing, the arms for example are full of jaggies.
- Bad color usage; for instance, you have a whole bunch of "brown tones" in the bag/face area that are barely noticeable.
- Bad color/pallette integration; for instance, the brown used on the head, could be used on the "skin tones" as a darker shade.
- Need of more contrast between shades (in relation to the above points)
- Weird shading; There are some parts where the shading/lightsource just doesn't make sense.
- Readability issues; In the cape for example, the texture just reads as randomness/artifacts
- There's some posture and anatomy issues; For instance, with the legs/feet, lenght, and the way it connects to the hip/waist.
Keep up the good job,
