great neat work...gl

This is a nicely finished model, its a little simple in my opinion but thats not really a criticism, i'd just like to see more of your work, see it as a compliment.

Really nice render. This is exactly something that would benefit from additional Photoshop help. If you were to soften the shadow edge a bit and gradually go lighter the further away it gets from the can...I think it would greatly improve and already great pic.

cool shapes author and very nice combination of elements....GL

This really is a good effort. I'm not really up on C4D, but could with a few tweaks to the particle system used for the fire this could be great. Well don author.

nice work author...gl

Nice modeling here. The motion blur somehow makes the blades look like they're about to leap off their motor. I don't know how you applied the blur? Or what render engine you used. But both Mentalray and Vray have excellent tools for just this thing. Nice job though author

I did use the blur tools in Mental Ray, maybe too much???

nice idea...gl

Certainly this is a good image. I read the SBS, and really would suggest turning the bump map down to at least 3, if using 3ds max. At the moment the planet looks a little noisy. Also for the material, I would change the shader from "Blinn" to "Phong" and set the specularity to 22 and the glossiness to 22. This will give a more realistic shine and reflect to the Earth. I don't know what render engine your using, But if your using Vray click the area shadows box and play with the UVW values to soften the transition from night to day. But overall a beautiful image.
