I like the composition of this image and I wouldn't change a thing. On the technical side, the white balance is a little off, which is casting a yellow hue on the milk. This image would also benefit from a bit more contrast and some noise reduction.
This image was a little hard to play with from the image posted in the challenge but I gave it a try anyways.
Post Processign Steps.
- Color Balance Layer: Reduce Yellow in both the midtone and highlights (Midtone settings 0-0-21 Highlight settings 0-0-25). The 21 & 25 are setting for the amount of yellow reduction on the yellow-blue adjustment bar.
- Levels Layer: Input Settings 20-1-255 (This increases contrast)
- Noise Reduction
- USM (Radius 1, Strength 100, Clipping 5)
I thought long and hard about how to pull this same thing off. In the end I went in another direction. Nice job...I think I Would have shown more of the center creme.
