i need more stuff in focus! a longer depth of field could help. the tag needs to be clear. i have a hard time with the raw reflection of the flash on the bottom of the glass.
If portrait 'upright' and teabag placed in full glass of liquid to show tea stain moving out and flashlit from side to catch transition and composed with more care.... this would have got more points - transition idea ok, just needs more application.
Did you mean to rotate this? I'm not too sure about the suitablility to the subject, but that seems like a common problem with this challenge, so I'm not going to get too worried about that aspect. The larger problem is that the composition doesn't really do much for me at all. The glass has some interesting textures on it, and I think you might have got more out of it.
With the help of the title and the tea label, I finally figured out what is going on in this photo. I think this is a difficult and devious angle for photographing a glass of tea.
i don't want to sound harsh, but it would have been nice to see some evidence of it being a cold night, like some steam comming from the tea or something like that.
