Haven't done a monthly chalange in a bit so this should be fun... like the theme too.
I'm going for man's best friend.... a 50ft Dog, auhh memory's :)
13598: love the idea and if you can pull off the lighting it'll be great.
Smolin: yours is ...em....well...ahh... i think there laws about that kinda thing :) should be good
Gabriella: looking good, the contrast between big and scary and girly is great, love the 50's look of the girl too. I'd loose the rope though, makes him look more like a slave than a friend
Dave: your monster has that "what the hell" kinda look on his face, i like it.
Mercurycat: the key hole really helps focus on the composition... wonder what his dentist bill's are like :)
Rageful: looking really good, not sur if leaving the background to the end is such a good idea though (speaking from a few bad experences)
