I like the shading on this one, so I don't even mind the total lack of shading in the background. I guess some pieces just don't really need a detailed background.

 Looks great!

Sublime, tienes mi voto.

Buen trabajo. Votaré por esta imagen.

Awesome paisano!

No pudo quedarle mejor su interpretación del April's fool. Buena suerte!

Los colores están geniales. Ya quisiera yo ser tan bueno hallando esos contrastes de color.

Yeah, the lack of polish on the heads is rather jarring, I think. Nice work on the focus, though.

I know somebody who needs his nappy changed.

There are some heads that aren't as detailed as the object of focus in this image.

Nontheless, I really like your dithering and AA technique.
