contrast/hue/saturation

Here's the finished version of my contrast/ saturation/ hue assignment. Turned out pretty good, I think. Probably could use some tweaking, I'll get around to that after the critique. I'm pretty sure the Hue one will always be ugly (its the last one). Any suggestions welcome. :-)

Color comp

Quick color comp :-I colors got a little washed out after converting to JPEG. Suggestions welcome, especially composition and color ones at this stage where everthing is just blobby and not worked out yet.
