My thought process behind this shot was to reduce the object to one shape, i.e. circles and this was done as two concentric circles by filling the cup with a liquid. Therefore the final result was the reduction of the cup to two concentric circles, one red and the other one white, on a white background, in essence, reducing the colour to just red and white in the shot. Again, this is purely my interpretation of minimalism. Reduction to minimum number of colours and shapes.

Regarding being closer to the edge of the frame, yup possible but I dont know why, I preferred it this way (tried various permutations and combinations and found this appealed to me the most) but will try again and see if I prefer it being closer to the edge of the frame. Regarding border, kind of wanted it like that (dont know why but I dont like my images without framing :-) Thanks.
