In the blue sky
I liked how the shadow moves across the image and designs a curve in the opposite direction of the reflective metal thing giving a decent balance to the image. Very simple, maybe the only distraction to the yey is cause by the inner reflection of the object. This render was made with an early beta version of Splutterfish Brazil R/S, some setting were cranked up all the way to make a clean and noise free render, however as I can remember the render time was something I’d like not to talk about! 
Let’s keep in mind the size of the images was 1600×1200 and the machine was an AMD Athlon 900Mhz with 512 MB of ram. For the blu reflections I use Dreamscape and set up a sikple sky with no clouds, some minor tweaks in photoshop to intensyfy the contrast.
