Well, I'll be honest. This one started out really nice, with a great view, perfect colors and cloud placement - but ended up a complete nightmare in the end. Plenty of cloud artifacts and crashes (mainly due to out of memory errors due to the foliage). I had to switch out the foliage at the last minute with other lower res versions to avoid these crashes. I had a perfect vantage point at first, but then couldn't get the foliage to "lay" properly art-wise, so ended up moving the camera for a better view. I couldn't get anything to look right after that. I nearly gave up on this one, but decided to complete it due to the sheer work I had put into it.
Sure enough, the final render had plenty of unexpected artifacts (mainly in the clouds). You'll notice I "smoothed out" some portions of the clouds in Photoshop (else it just looked annoying). Luckily it wasn't much work at all. The image was a standard 4:3, but I had to crop of the bottom 3rd of the image due to the foliage not laying right due to the camera moves.
Stats:
Render time: ~20 hr
Res: 800x600
Quality: 0.8
AA: 16 (for the foliage - it needed it)
Other than the cloud smoothing, only minor color adjustments, lighting, contrast, and selective sharpening in Photoshop. This gives the images a little something extra. This one needed it.
