Thunder, don't sit out for that, dude.  I know I did for the Architecture challenge, but that's due to 3 reasons.  The major one being that I SUCK at modeling.  I mean suck rocks here.  Second, I didn't have even a good concept until the last 48 hours of the contest... and I 'm working 60 hours a week so I have no time to do it.

Besides, my application of the model broke so many of my personal rules for creating a scene... it was gross.  I'll be trying to do it again some time....

But don't just sit out because you don't feel you can compete.  This is when you usually learn the most, when you're driven to do something like this.  I didn't get noticed till like the 3rd challenge I participated in.  And the one I may have come in 3rd in, was never tallied.  (nudge nudge "creepy, 06" nudge) ;c)  Just give it time my friend, sometimes it just takes the right inspiration and timing and you can win it all.

Well, that's my pep talk. 

To the OP, I'm intreagued with a monochrome "color" and white comp, but can't that just as easily be done in photoshop?  Primitive only I guess I'll get to do my first sphere over water finally... LOL
