a nice idea, but the colour balance and the tilted horizontal really don't help. if the milk was white, that would help a lot. there are tutorials on both removing a colour cast and straightening horizontals. the focus is good, and the composition is quite good.
Seems to be a common theme. This shot is hurt by the distracting elements in the background. Lighting is pretty good and I can still read Nikon, which is also good.
heheee... yes. good focus on the hand and top of the glass... maybe a little more contrast, sharpening and cooler color scheme could help this photo out, nice job controlling potential glass glare, and nice set up, keep up the good work
