I like the thick lines that make up the general shapes throughout the piece.

It really helps give this stylized look to the character.

I think you could add a bit more to the piece to make it more striking and catching to the eye.

Right now you only have the flat shading on one half of the body. It would be interesting to see some highlighting on the side with the light source.

I also think that incorporating the shadow of the figure on the background could help give it some grounding.

Or, you could do a background with just simple blocks/strokes of color with no outlining and to help set a scene.

I hope that my critique wasn't too negative or anything, just want to point out some stuff.

Hope to see you improve with the next pieces.
