Eh? Well I have this image here, There's something about it that I can't really put my finger on? So I figured maybe I'd try posting and seeing what you guys have to say and see if you can post some ideas on how I can improve it.
That's a very nice image.
As for things that could be better: It may just be the gamma on my monitor but I lose the outline of the glass against the white background.
It's hard to tell because of the angle and the lack of background but do you have the index of refraction set properly?
I'd also expect to see caustic highlights on the ground. And darker shadows.
Hope this helps.
