Nice closeup...perhaps a little more focus or a bit more white frothy foam and I would have scored this higher. I like the lighting in the upper right.
Heh. Bubbles galore! I think the composition is decent, but the lighting could be a bit more dramatic and add quite a bit of depth to the image. The brightness on the right is very distracting. I'd suggest having the light set to diffuse through the liquid to highlight the richness of color. I think an image like this also needs a dark background to act as a contrast and also help pump up the hue. The title mentions head and so that's where my eye goes for a focus, but much of the foam is unfocused or obscured in shadow, so a fill light of some sort might help bring those details out. The idea is good, there is a lot of aspects to work with but despite the foamy nature of the image, this one leaves me a bit flat. I gave a 3.
