Creative choice of effect. Could be better if you'd rotated the camera, and shot this vertically and caught the whole glass/ vortex, rather than having so much wasted space on the sides.
A very interesting idea. Wish I could see the bottom of the funnel, though, and more controlled reflections / better light. A vertical might work better here.
I think a vertical shot would have been better for this. That way you could have gotten more of the glass in the shot. It is a great idea, but I think it could have been done better
I like this alot. But, I think it would have been more interesting head on instead of from the top. Or maybe if you had pulled back a little. Either way would have added more interest (imo).
