Thanks. :-) 18 out of 20 isn't bad. It's tough to put in really original techniques with a limited color palette like green, but I see where you're coming from.

I thought about this one for some time. I like the concept, and the effort you put into it certainly shows - but... The build just doesn't wow me at all. There are no "that is a cool concept/technique". The pictures are nicely done though, which is always helpful. Three (3) points. Lee.

Very nice! good color choice for monochrome!

Good job. Lots of cool set-ups here. Clever use of a tough color; plus neat spin on the color. 5 points.

Great color, great message. 5 points, the last of which granted to your marvellous take on the concept and build.

Nice job! The colour fits perfect with the message you delivered. :)

Nice, I like how you put in the message too.
